What about in future ?
Possible using modified e.g: Caetla or PAR.rom to using cheat codes and could manage them with savegames etc ?

this is a dev cartridge, not a game cheat cartridge.

Hmm, I just tried to send some constructive or motivating feedback yeah like, "you could redo the whole thing using STM32" .... not very motivating on my side. But if you want to make it faster I never asked for that, you told me it could be faster, I don't care, I just want to get someth...

The FTDI specs say that the chip could support 1Mbyte/s, so it looks as if you are doing something wrong. Are you executing your program code directly from ROM, in an uncached memory area? That would drop the CPU speed from 33Mhz to somewhere below 500kHz. Or are you reading/writing lots of USB con...

Only an USB FIFO, and some logic, without any microprocessor? And the photo looks as if you have a huge eprom or something similar...? no microprocessor, there is an eeprom of course for the software that handle the data reception and executing. the pcb is a prototype with a bunch of debug stuff, t...

What chipset are you using? Minimum would be a single chip that could both simulate a boot rom stub and manage the usb transfers. I'm using an FTDI USB chip FT245, an some 74 logic chip. I'm not skilled enough to do fpga or stuff like that, this is my first real electronic project. Do you have a re...

I am currently developing a cartridge for Playstation 1 which plugs into the so-called "action replay" connector. This cartridge has a USB socket and allows you to transfer data from your computer to the PS1 via a Linux/Windows compatible tool. (bi-directional) this makes it easier to deve...

I can confirm that the PSX Blaster design doesn't work. I simulated the logic in a software and it is wrong, RD_USB goes low require AD17 AND !AD17, which is impossible. Also, the logic voltage are mixed up, some logic chip have 5V, some other 3.5V, and the USB chip receive 5V logic on its pin where...

last call if you would like to see a physical version of these games on Playstation 1, please pre-order on my website https://www.orionsoft.games/
otherwise, too bad, I will only do downloadable content

I made a making of video of my RPG Zia and the goddesses of magic for the Playstation 1 i'm also planing a re-edition with a new artwork, Pre-order is available on my website: https://www.orionsoft.games/ https://www.orionsoft.games/retroshop/zia_ps1.jpg The video is in french for the moment because...

well, no ps1 version then

I am proud to present to you my new game project Alice Sisters. Alice Sisters is a cute platformer game using 2 players co-op mechanics, the game was already released on the SEGA Megadrive/Genesis and Dreamcast console! The game is currently being ported to the Gameboy Advance and Atari Falcon, I'm ...

I had this idea in mind since years, but never took the time to actually work on it, (and I doubt I have the skill to reverse engineer the bios code) so, very nice job on that ! as someone already pointed out, you can use my memory card manager tool to import a save to a memory card easily using the...

Do you mean for PSX Blaster ?

yes

I'm thinking of getting a newer PC and getting rid of my beloved parallel port in the process the only system that I need the parallel port for, is the PS1 with my xplorer FX + caetla so I would like to replace this dev setup with a modern one using USB I know an AR cart was in development here on t...

I updated the PS1 version of Zia and Yopaz so they can directly be played using the PSIO flashcart!
(CU2 and BMP cover included)
Enjoy -> http://orionsoft.free.fr

well, I made several games on the PS1, so I know the C language pretty well but I did not really got in depth low level stuff on the PS1, just relied on the PSYQ SDK for now. I know the no$psx documentation is pretty well documented for low level stuff of the controllers. I might have access to a li...

I'm interested in this too, I like strange hardware for the PS1
I just bought a controller like this and hoping to mess around with it so I can display some custom message
(I'm not an electronic engineer though, so any help on the protocol is appreciated )
