PS1/2 Is There Any Old PS1 Hacks?

[neoncelery]

Ok guys so in conclusion me and my friend have decided to stop. There's no way of playing burnt games without altering the system in one way or another and we don't want to vandalize it since it holds so much sentimental value to us and his father. I have decided to just save up and buy a PlayStation 1 classic and other little classic consoles which our way more simple to hack so our love of retro games can live on. Thank you all so much for all your help you guys are lovely~ till next time take care gamers

Hi, me and my friend got this old PS1 his dad gave us and like the scum we are we're trying to find ways to hack it for free games. We have a bunch of empty disc is there any ways we can dump games onto those disc and pop them into the PS1???

Stupid right? :'D

softmodding is a joke on PS1. Get a PS3 and play PS1 gamers from there.

Do you have an I/O port on the back?

You can get an action replay and connect it in the back

This will make using the swap method work 100% of the time.

The action replay stops the motor for you and gives you ample time to switch the disc

I have something called "Mini Goldfinger" which is pretty much what I just described.

You can get one on eBay for 10 bucks

Also I feel it should be noted that the quality of the ps1 isos you use is important. I found this out myself when I first did the swap trick, before I went and installed a mm3 modchip. The arduino way would have been better yet, though.

Still, the best is if your ps1 is compatible with the PSIO, which you basically have to solder a couple of wires and then you can run from the serial i/o parallel port behind certain models of the ps1. I have a ps1 that supports this but I don't have the money....

I wonder if the ps1 memory card could be used to make the ps1 boot into the serial parallel port? Kind of like how fmcb works for ps2 since the memory card is accesed early in the boot. It would make the PSIO more accessible to more people who don't want to hardmod.

First of all, the PSIO fits in the parallel port

Even then, it's not an actual parallel port accessory (which could autoboot just fine, if it was), but an ODE - it really needs that internal card to disconnect the optical drive and replace its signal with that coming from the parallel port (it's like those pci expess extension cables where one of the parts is an USB 3 cable, chosen because it's a common and affordable 9 pins connector, not because it has anything to do with USB)

To answer the literal question, you can run software from the serial port (that's how the Yaroze works, apart from the gratuitous added DRM to the official boot disc to make it incompatible with regular PS1s) but not only it's unsuitable for commercial games, you would need a boot disc (or ODE) in the first place

There can't be an equivalent of FMCB, because the official firmware doesn't run programs from memory card (again, boot disc, boot-parallel-card, or rom replacement required) and up to 2x128 KB are even more limiting than the almost 2 MB you get for running homebrew from serial

Ah, thanks! Corrected the original post. Interesting info about the actual serial port though.

Would it then be possible to swap-disc into some boot disc for the serial port and have some program run from that, that would redirect to the parallel port.
Or is that only possible on the yaroze models?

I imagine the transfer speed of the serial port isn't fast enough to allow using it to run games, kind of like how the ethernet port is used for that function on a softmodded PS2?

In theory yes, but it would be a bad idea:

• A well designed parallel port accessory can autoboot by itself (since it can override the firmware)
• Once you can run non-original discs you might as well skip the intermediate step and use a program directly on the disc to interface to the parallel accessory (not the PSIO for the above reason)

It is indeed slower than an 1x CD (115200 bps seems to be the maximum speed supported in the official SIOCONS interface software, and there's at the very least 2 bits of overhead every 8 significant ones) but the bigger problem is fitting in memory some software to hook the game and redirect optical drive read commands, OPL and Wii CIOS for the most part do not have this problem since most/all of the job is done on the separate kernel processor with its own memory the game won't mess much with (at least directly)

So does that mean that instead of an ODE like the PSIO, it could be possible to have something like the saturn satiator for the parallel port?
