Here is my Kickstarter for a tool I have been working on since about 2 months It's called "Retro Game Designer" and it's a Windows / PC tool that will allow you to create your own video games and export them to the Sega Megadrive, Dreamcast, Playstation 1 and Atari Jaguar consoles! Without...

ok, I didn't know the gamepad and memory card bus was shared.
that's kind of messed up ...

I have a memory card like this but with a physical button on the memory card to switch bank. How is it possible without a physical button ? I don't understand how this memory card can tell the playstation to trigger something from the gamepad ? Wouldn't it require some custom code to be injected in ...

You may also want to remove the modchip connection for dumping. It may interfere. I have no modchip in my net yaroze. I will dig out my Arduino and see if I can find out what the problem is - my guess is that serial.print() is blocking long enough to miss the start bits coming out of the PSX and th...

ok so it took me about one hour but I eventually got something (after wiring GND from the PSX to GND from the Arduino, else I only got 0xFFs) But the 3 dumps I got are all different .. I used my Arduino Uno, but since it only have 2Kbytes of RAM, I can't store the entire CD bios into the RAM, so I n...

Apropos. Any news on dumping more retail psx cdrom firmwares? I had hoped that dozens of people would their firmwares... like people implementing it as "my first serial data transfer project" using an arduino or the like... but now it's more than three years and only 3-4 people managed to...

search Xplorer or Xploder on ebay you have plenty of these

I tried this tool because I needed to upload a program to my PSX without using the AR port (no Xplorer FX) I made a CD with Loser PSX Menu selector, and when launching PSX Serial I get a black screen, maybe they are using the same memory area (end of ram), so I tried to launch PSX Serial by sending ...

Thanks very much for sharing ! Do you allow me to put it in the next X-Flash mod update ? Your rom is missing from our set. Yes of course :) I don't have a GB game so I could not check, but yeah, from what I saw after a quick disasm of the emu, the GB Rom gets mapped at 1F040000h by the PAL. At lea...

ok I took some time today to write a little program to dump the ROM, pack it and write it onto 2 memory card so I could retrieve the data on my computer using my USB PS1 Memory card reader tool. I verified the integrity of the ROM using SHA1 algorithm computed directly on the PSX Here is the file: h...

Great that the ROM have been dumped, maybe we could understand how the hardware is used to dump the ROM and emulate it, then if someone with lots of motivation could make a better emulator, we could reflash the hardware with this new emulator and it would be much more usable

does your bin file have the correct format ?
can you post it so I can analyze it ?

the limitation would be the GPU speed, and the vram size Some PS1 games renders in 480i but this require the game to run at 60Hz, which means less texture, less detailed 3D models, and this uses almost 3/4 of the vram space just for the game image (so, less texture space available) an example is Tob...

I guess, the 4.7 sdk only changes the library, not the compiler.
just unzip the 4.6 sdk files and unzip the 4.7 sdk on top of it,
you will get an uptodate 4.7 library with a 4.6 compiler
I did this and it works fine.

1 c'est de rassembler tout les fichier du programme du multissession loader en un exécutable pour le faire marcher sous MCLAUNCH Je ne pense pas que ça soit possible de faire ça, MCLaunch ne lance qu'un seul exécutable, tu peu peu pas combiner plusieurs fichiers avec. et surtout je ne vois pas ...

c'est très difficile de te lire, j'ai vraiment du mal à comprendre ce que tu veut faire, c'est une traduction automatique ou quoi ? quel est ta langue d'origine ? transformer un exe en rom ce n'est pas si simple, je ne sais pas si un outil existe pour faire ça je pense que tu te complique beaucou...

je fait mes premier pas en développement alors voila mont but pour l'instant c'est d’accéder a mes carte mémoire sous MCLAUNCH a moindre cout de bruler de cdr et le premier exe que je veut lancer c'est le programme multissession loader sous émulateur ca fonctionne mais il reste bloquer sur ge...
