Will a Mini CDR work on a PSone? why just it does

[Ponlork]

if i make a PS1 homebrew i'll like to release it on Mini CD just to be different. they typically come in 180mb and 210mb. ironically they cost much more than standard 700mb CDRs. I got some TDK 24x 210mb Mini CDRs, i burn it at 4x and im using freepsxboot to launch it

Why not just burn your homebrew onto regular size CD-Rs? Not only are mini CD-Rs not manufactured by top manufactuers anymore, but finding "new" old stock is relatively difficult to track down. In addition to availability, you also have aftermarket mini CD-Rs which don't play as nice with, say, the PSone/PS1 due to them being of poor quality and the laser struggles to read them.

@alexfree has a full guide on his GitHub Sites for what burners/rewritable media to use-if you're curious. Avoid anything, that is, Verbatim AZO, Maxell, Memorex, or any no-name/cheap supermarket brand, as you risk putting more wear and tear on the laser, as if the lasers are already failing from age. https://alex-free.github.io/psx-cdr/

just gimmicks. to be different. i like the way it look. plus it can fit in my playstation classic if i ever modify it to add a mini disc inside.

sometimes u just need to find something unique that separates it from the rest, even something simple as the size of the disc. at least that's how my mind works. but in many cases, like with games such as RPG Maker, if they all use the same effects or scripts then people may become blind to it. but then add a little difference like a custom BGM, custom assets etc and people are suddenly intrigued.

reminds me of the early days of ebay when they didnt have thumbnail galleries, it was just text. but then someone found a way to hack the title to add a animated gif and it got millions of hits. not that seeing a animated gif is anything specular, but like i said, gimmicks. sometimes little dumb shit like that is what gives something an edge

and for some creators, just finding something different is enough to keep them motivated. whether its a unique feature in a game, or something that separates them from the rest. it could be as simple as adding a CRT into a Arcade1up, or adding a coin door to it. if its different it might make it more interesting

I'm totally not into watching random long YouTube videos. Is this an actual question?
A CD-R is just a CD-R (Orange Book specification) There is no reason for the PS1 to not work with 8cm discs. They were briefly used for singles (music). Almost all commercial games are bigger than the capacity of Mini-CD-R. I've used some old mini CDs on the PS1 myself for testing. Good quality 8cm CD-R are pretty rare. Go for 185MB ones.

Even irregular "shape" CDs should theoretically play on the PS1 → But for heavens sake don't put strain on the aging mechanical parts by using credit/business card CD-R or heart/star/Diddy Kong shaped, imbalanced music CDs.

i feel some people may be unaware as i've never actually seen someone try it. if i could press my own discs with the wobble groove im definitely pressing it onto mini CD because in a sea of standard sized PSX discs, a mini sized one would stand out. and plus i jus want to, that's all the motivation i need

Pressing discs with deliberate tracking error isn't trivial. You can look up the patent online. It describes in very vague terms how it is done.
I doubt normal pressing facilities can do it.
I've been reading up everything on the topic I could find for years every now and then. Other than an impressive but limited proof of concept abusing Yamaha DiscT@2 to fool the detection I know of no self-booting discs. My skill level is too low to hardmod a CD writer. It might be possible to inject tracking error with an arbitrary waveform generator.

Copy protections for console discs are a beast compared to those on PC games. Having known hardware one can define characteristics out of range for normal writers (and readers → this is why PC protections couldn't make use of such tricks).

a mini sized one would stand out. and plus i jus want to, that's all the motivation i need

If your stuff fits on small CDs, why not? In case you actually have a pressing (with or without the protection), quality problems of cheap currently available mini CD-R don't apply. A pressed CD for PlayStation ideally has a slightly larger track pitch than the commonly used minimum the CD standard allows for maximizing capacity.
Ideally your content stands out, not the storage media.

Good luck!

One potential downside to the mini cd is that they could be annoying on a PS2, at least it was the last time I tried one in mine.

yeah ive been following it off and on over the years, reading threads on psxdev and there was a user who got close to getting burned discs to run on a stock ps1 though the success rate wasnt consistent.

as for pressing discs, ive seen some companies like Datel and Breaker Pro who were able to do it without Sony, i imagine it's not something a regular person can do unless they're loaded with cash. but if its possible then i'll keep the dream alive

and thanks, its just a idea of mine that'll probably never come into fruition but its fun to fantasize. i'll like to package it in something like this

hmm i have a fat ps2 i should try it. is there any reason why it'll be problematic? i can understand for a PS3 or PS4, now im curious if a PS3 would read mini discs properly, im thinking it'll get lost in there lol

ive seen these mini cd to standard size cd adapters, maybe i can bundle that in too if i ever reach the finish line.

Years ago I bought a large cheap MC which required a mini-cd to enable, even with this type of adapter I couldn't get it to work in mine.

edit:

My console is a phat 5003 model which I keep vertical.

 

[Ponlork]

that got me wondering... would a 100 min CDR work on a PlayStation? i'm thinking it would but ive never seen anyone try. maybe i'll grab a hold of some. i dont think any retail PS1 game actually exceeds 650 mb, but they can be burned on 700mb so i'm theorizing it should work. but can we utilize the extra space of a 100 min 900MB CDR?

Thin Ice Media manufactured Datel discs. Success HK who manufactured the PS-X-Change did the Breaker Pro discs; they stole asmblur's work by re-labelling his Import Player as "Breaker Pro", removed the credits, and changed the background to black instead of the blue-green gradient-such a dick move if I'm being honest if they're selling it for profit, the original "Import Player" program is free to download.

thanks for the info, i'll have to check them out. and yeah credit stealing is rather prevalent even in the open source community. i kinda equate them to clout chasers, the type who would take someone elses work and slap their name over it and then minimize the original authors

so im scouring for some 99min and 100min cdrs but they are very rare. i found one in japan but i think it's a mislabel. zooming in it says 700mb

Avoid getting the 900MB CD-Rs, they're absolutely not worth your time for PS1/PS2 games. You can only overburn data with these discs as it doesn't work right out of the box unless you have a supported drive which can do it (see here), then again, the PlayStation will have a difficult time reading the pits on the CD because of how tight they are, and could strain out the laser. Order 650MB or 700MB CD-Rs which is about enough for one game.

It won't work (correctly). PlayStation 1 as well as many cheap CD drives struggle following the narrow tracks on 90/99/100 minute CD-R. High quality audio CD players often read them correctly. DVD drives and standalone DVD players usually accept them (including higher read speed for SVCD).

Using higher density CDs than 74min/650MB reduces compatibility and reliability (longer load times, full motion video stuttering, skipping audio streaming). Especially early PS1 models struggle with this.

Also no luck with GigaRec either. CDs get detected with GigaRec 1.2 but no higher. Doesn't read reliably.

I have done these tests a few years ago and not very in depth. My memory is a bit blurred. If you want I can test high capacity CD-R. Don't laugh: I have roughly 150 of them lying here (five different types).

i'll like to try. i dont mind it failing. i do recall seeing dreamcast isos being released in 99min and 100min cdis. back in the day a lot of Dreamcast games would exceed 700mb so they would have to remove or recompress FMV scenes out of games in order for it to fit onto 700mb. but considering there were 100 min CDI images im going to assume they worked on dreamcast

did you play Sakura Wars on Saturn or Dreamcast? its not often that visual novels get translated, but ive always wondered why dont people translate games like Sakura Taisen, Love hina, Kimi ga Nozomu Eien, Air, Kanon, Snow, even Ever 17: The Out of Infinity which made its english debut in 2025 on the Switch was originally a Dreamcast game.

instead we see translations for Di Gi Charat Fantasy and im like come on. and im not even a visual novel fan but i collect imports and i see a lot of these visual novels on the consoles that never seen the light of day in the US

 

[KleinesSinchen]

Welcome to another lengthy Sinchen post. I just can't resist doing some tests again…

I have to correct my previous statement: At least a PlayStation 1 with good condition drive is able to read relatively reliable from high capacity CD-R. After trying a 90 minute CD-R in my SCPH-9002 for some minutes, including randomly selecting titles and fast forwarding, I searched for a music CD with about 100 min.

The result surprised me. I noticed one single instance of (wrong/bad) interpolation indicating a read error as well as very brief pauses between some titles. Listening for almost 100minutes with full concentration is out of my range, so I might have missed some tiny errors. The one interpolation error I noticed was very subtle. Either the PS1 read the disc almost perfectly or the audio interpolation is outstanding.
For a worn PS1 drive the results are less convincing. My SCPH-1002 – which requires maintenance – detects and starts playing the disc. But it skips just because walking next to the console. Selecting titles near the end resulted in strange noise and the disc stopped.

The limited test shows that a PS1 is able to follow the narrow track and can address sectors above 89:59.74. I can’t test beyond the magical limit of 99:59.74 which crashes many devices. My custom Beatles “1967-1970 / Blue Album” on one CD-R has under 99min.

What the limited test does not show: if a game disc with narrow track would be readable in reliable manner. For game loading and video playback the drive goes to 2x speed and games require frequent random searches. Read errors for program data are fatal. They requiring retries opposed to merrily continuing after an audio glitch the listener might or might not notice.
I will burn a backup of a game with voice acting and full motion video on 100min CD to test if it is acceptable, but obviously I can’t test access beyond 71 minutes since there are – by design – no bigger discs allowed officially.


What we would need is a homebrew app implementing a subset of Nero DiscSpeed for testing sequential reading and access times for random searches on inserted CDs. That would be helpful not only for non-standard discs, but also for more objective quality/compatibility control of various CD-R.


Here are pictures and ATIP data of some high capacity CD-R

Spoiler: Old 99min

"Jackling" → intended to convert DVD movies to (S)VCD with the Movie Jack software (became illegal shortly after being published – sadly the software was not present anymore when I found the old package on the flea market.
"Parrot" → No idea what this is. It looks like some CDs. There was no parrot in the box.

Both can be overburned to 99min but both kinds showed failures at the outer most parts

Spoiler: Media Range 100

Two different kinds of 100min CD-R labeled Media Range. Still available new, cheapish. I have almost 100 of the inkjet printable kind → ready for testing.

Both kinds can be burned up to 100min. Some discs worked when reading the outer most part, some not.

Spoiler: 90min

Verbatim, still available, cheapish.
TDK Metallic. Non-standard ATIP advertising the capacity of 800MB/91min. No overburn function required to make use of the full capacity. Since this violates the standard, some burners detect the CDs with a puny 11 minutes (overflow at 79:59.74) instead. Very high quality discs.

Lastly when not considering a non-standard storage medium as "selling point", these 74min CD-R perform almost as good as pressed original PS1 games.

Spoiler: Boeder Gold

I've used one of these for a PlayStation backup. The result had just four(!) C1 errors across the whole disc when checking with Nero DiscSpeed. These things are rare and expensive, but they would be excellent for distributing a homebrew game.

thanks for the comprehensive tests. it's cool you got different brands, the only one i can find thats still available today is mediarange. i figure i should try to get as many different brands possible because i know for regular ps1 burning, some brands dont work. but these days 100min cdrs are pretty rare.

as for testing homebrew, my initial video is actually a combination of 3 separate games, RPG Maker, Raiden Project and Mike Tyson's Punch out via imbnes. i modified RPG Maker to launch external exes via the text box. So my idea was to bundle multiple games and have like have a arcade room where the character can launch different games.

there is a homebrew by lameguy called Meido Menu which lets you add multiple games on one disc


might be worth checking out if you wanna try burning a game discs that exceed 650mb

 

[alexfree]

Why not just burn your homebrew onto regular size CD-Rs? Not only are mini CD-Rs not manufactured by top manufactuers anymore, but finding "new" old stock is relatively difficult to track down. In addition to availability, you also have aftermarket mini CD-Rs which don't play as nice with, say, the PSone/PS1 due to them being of poor quality and the laser struggles to read them.

@alexfree has a full guide on his GitHub Sites for what burners/rewritable media to use-if you're curious. Avoid anything, that is, Verbatim AZO, Maxell, Memorex, or any no-name/cheap supermarket brand, as you risk putting more wear and tear on the laser, as if the lasers are already failing from age. https://alex-free.github.io/psx-cdr/

To be fair the laser is so “stupid” in old models it just wont read it. Now your right for SCPH-5500+ to an extent, but still in my personal opinion don’t really think it will cause it to burn out just read worse. This wasn’t really a problem until PS2 with CD/DVDs IIRC. And maybe some other consoles a bit newer than PSX. But yea, pure analog servo on Og launch PSX.

And I mean yea your CD could be a F’n star shape if you wanted but with the amount of issues the console already has (and this applies to at least fat PS2s as well) with higher density media (which is everything higher then 71 minute/74 minute) your kinda just asking for trouble unless your strategically putting a good dummy file on it if it’s any significant amount in size.

Ok I seriously question this because you’re using an audio track. With a data track there is a fatal flaw in tracking the sync header which audio tracks lack. Sony knew about this in at least early 95. The issue always was MASSIVE seeks from say sector 25 where system cnf is to say sector 300000 where the PSX executable was which system cnf told it to go to was. The higher density media was just too dense to make the approximation expected for lower density to not overshoot and cause the drive to lock unless you added an immense amount of dummy data. In your test some of the audio data is acting like a band aid. If it was completely unburned data the drive would get completely lost and lock up.

The PSX drive is stupid. It thinks anything is 71 minutes disc. Because sectors are longer on 71 minute discs then 74, 80, 90, or 100 exponentially it gets the distance to move the laser more and more wrong. It basically makes a best guess where sector xyz would be from the spindle if it was a 71 minutes disc. If it is a 71 minute disc (like a real pressed cdrom PSX game disc or developer disc) then this is pretty accurate. But sectors get a hell of a lot smaller the more and more the density goes up. And gets to a point where it just straight up seeks inches past even the last part of your disc that has burned data is. And when the PSX reads unburned data it looses its mind and shuts down forever until you power off

If you want to prove this, go ahead and burn krushi pal on a 100 minute CD-R.

not sure if Meido Menu uses a Audio Track but my method is using mkpsxiso which is rebuilding a ISO so it's still one data track. basically rebuilding is like when you rip a game's contents, and you add additional content on the disc, IE a second game that you also ripped, then combine them all together into one ISO by using mkpsxiso to build it

it dont have to be a secondary game, it can be appending more data, like in my RPG Maker example, i added additional BGM music by appending more seq+vab BGMs at the end of the SOUND0.BIN file. you can add additional EXE demos, games, images, or any files you like.

as for any risks, meh i dont mind. it can blow up my PSX, im not really concerned about any risks. i like to experiment
