I am using postloader and then using the DM or DML Booter from homebrew channel (whichever one is the USB one) and I havent done anything update wise since it worked. but I did update postLoader from the in-app updater but thats it, no wad updates or uninstallations or any of that

Okay, I don't keep up with Postloader but last I checked, there WAS an option to indicate what version of DM(L) you have installed but they were PLANNING to remove the setting and have it only support DM(L) v2.2.
(This error usually means the loader is trying to run DM(L) as if it were a different version)

I can see two possibilities (kinda guessing here):

You had an older version of PostLoader from before DM(L) v2.2 without the setting. When you update, the new version defaults the setting to v2.2+ the first time. All you'd have to do is change it.

You had the version with the setting I mentioned earlier but you already had the setting set to the older boot method for BEFORE DM(L) v2.2 and you updated to a newer version that no longer supports older versions of DM(L). You would have to update DM(L) to v2.2 in that case (Which would also fix situation #1)

(One way or the other, I'd ask on the PostLoader thread to see if the newest version available by the in-app update feature is still compatible with older DM(L) versions and if so, where the setting is to fix that.)

I select the DML 2.2 from the postLoader selection menu but it doesn't work, still loads the disc in the drive. same thing happens from the DM/DML booter from the hbc so i dont think that it's postloader :/

Are you sure you have 2.2 installed and not something earlier? Try the "new 2.1-" option in DM(L) Booter instead of the "new 2.1+" option and see if it helps.

Alright i will try. How would I update to 2.2?

You'd go here : http://code.google.com/p/diosmios/wiki/Downloads?tm=2 and download the DIOSMIOS_2.2.rar file. There's a WAD file in there that you'd install with any WAD manager and you'd be done as long as it doesn't give you any errors while installing.

I didn't install it but from the dml booter menu I chose new instead of old and it works now

I'll install the latest version later

DM 2.2

Are there compatibility differences between DiscEX and GCReEx?

SuperrSonic · Sep 5, 2012

Is there a way to rebuild the fst without using neek? Like a console app

Yes. Basically, everything works in DiscEX (Depending on the options you use, it's just a copy of the whole disk image as is ... which is as compatible as you can get) GCReEx doesn't work with some games but it can be faster loading.

GCReEx

In a word, yes... You see in DiscEX almost all games work, some need to be not compressed though, however not all games work in GCReEx but there's one game "as far as I know of" that works in GCReEx but doesn't in DiscEX and that is Phantasy Star Online Episodes I & II!

iffy525, since you are using DM 2.2, i would suggest you not compressing the games at all, that way you don't need to worry at all about compatibility.

You definitely get better load times with GCReEx. That's one reason to not use DiscEx images. The Google code page only lists 9 games that don't work in this format, 4 of which are demo discs. You can use images for those. It's not an either/or decision.

I installed Dios Mios Lite v2.2 and tried to load games via usb using CFG usb loader. It gave me an error saying there's not enough space on my SD card. Why do I need space on my SD card to launch a game from my usb? o.0

It probably thinks you have DML and it's trying to transfer the game from USB to SD so that it can run.
Check the loader's options and paths to make sure it knows you want to launch from USB.

Lol the problem was that I DID use DML and not DM. Stupid me. Got it working now, thanks !

Faster loading times then an uncompressed iso? Thats new to me... point is most USB devices have plenty of room, therefor i think you can save yourself the trouble of compressing at all.
DML ofcourse is a completely different thing.

As far as I know, neither GCReEx nor DiscEx actually "compress" the data. DiscEx with the -c option, simply deletes the garbage data from the ISO, whereas GCReEX extracts the files in the ISO with -x and rebuilds it with -c.
The loading times when using the extracted files is faster than when using an ISO, scrubbed or otherwise. This is even more so with cards formatted to 32kB cluster size.

I'm using 1:1 dumps from my disc, and I'm fully satisfied with the loading speed. I don't care if it's 0.02sec instead of 0.03sec! (irony)
I'm already glad it can be launched from a loader and I don't need to swap the disc each time.

I personally don't see any use of compressed/extracted format to get a higher loading speed, but users seems to care while it's already faster than disc loading?

I definitely don't. In fact, Skies of Arcadia has the same problem with GCReEx as it does when compressed. GCReEx does work much better with DML though.

Not really.

When I was testing DML heavily, I did a lot of benchmarks with F-Zero GX, because I actually noticed the load times for some screens were longer than I remembered them. If I had not noticed it, it would not have been a problem, but noticing it prompted me to explore all options. For consistency, I measured the time it took to load the track selection screen after selecting one of the first four cups in Practice Mode (the fifth cup had longer loading time than the rest).

Here is what I found on my 32GB Lexar card:
- real GCN disc: 2 sec
- DiscEx format on SD @ 64KB clusters: 2.5 sec
- DiscEx format on SD @ 32KB clusters: 4.5 sec
- GCReEx format on SD @ 32KB & 64KB: 1.0 sec (both)

- DiscEx format on USB HD @ 32KB clusters: ~4 sec (this one I don't recall very well, but it was slow)

- GCReEx format on USB HD @ 32KB clusters: slightly less than 1.0 sec

So no, it's not milliseconds I'm talking about here. Now, some games don't have this issue at all, as far as I can tell. I never noticed any slowdowns with, say, Mario Kart Double Dash or Super Mario Sunshine. It really depends on the game and I did not test that many of them but I decided to optimize for the F-Zero GX worst case to avoid slowdowns in other games in the future. Also, some cards will have faster load times than others, particularly smaller ones. I tested DiscEx @ 64KB cluster size with a smaller card I have and the result was 2 sec, the same as the real disc but not as fast as GCReEx.

Knowing it is faster, I really see no reason not to use GCReEx, except on the few games that don't work with it. Once you extract the files, there is no additional maintenance required, so it's a one time effort.

Of course going from 4 seconds to only 1 second is good, but my point was that a 3 seconds loading screen is still bearable
