So, um yeah, what would be the best option for PSone home coding? Either hunting down a full Yaroze set-up (which I assume is damn expensive now), or a modded PSoriginal, with Cheat card, over-written with Caetla (sp?), and the PC link card? What software is the best to use, and will the Yaroze stuff work with Caetla? Cool, cheers..
Yaroze will only work on a Yaroze, Yaroze tools are only for Yaroze ;( If you have a Yaroze however, you can get evil tools to make standard executables out of Yaroze files. Caetla (PAR/ARP/GF/GH) is the cheapest way to go,you could get the whole setup for less than $30 if you try. You'll need an ISA slot though and a bit of patience, by no means is it easy. As I understand it, the Yaroze can only "do" game s up to 3/4mb I think, can't remember. Everything is executed in RAM. Caetla should be similar because you'd be uploading it to RAM or flashing the cart with your code which would give you 1M/2M (depending on the flash cart you get) or 2mb if you upload to console RAM. Which route you choose to go is probably answered by: "which programming languages do you know"? If you're very comfortable with MIPS and PSX hardware, maybe the Comm link route is better, if you know C and wouldn't mind getting a very expensive piece of hardware, get the Yaroze. Bear in mind that if you do the Commlink/Caetla way, you'll be only using (mostly) 3rd party tools.
You can also use the Yaroze setup on a regular PSX - the PC-side software and image of the boot disc can be found somewhere in the depths of the internet, and you can either use a gameshark code or a patched version of the disc image to bypass the need for the special memory card. As for getting software from the PC to the PSX, I believe the Gameshark Sharklink cable is essentially the same thing as the supplied Yaroze serial cable. I used to know of a site that had the gameshark code for the access key, I'll try and dig it up for you if you want. Bear in mind that as Kyuusaku said, the Yaroze is really limited in the size of the games. I think 3-4 MB was even too generous - didn't the PSX only have something like 2MB of RAM?
Yeah but I think the Yaroze has 4 or 8mb of RAM. (Unlike the blue debug which REALLY has 2mb) I know games must be limited to either 3M or 3Mb, I remember that 1M/1Mb (can't remember which) is taken by Yaroze stuff. I could use that Access Key GS code if you can find it GSL
Use Caetla with the comms card + PAR or Xploder + parallel port I'd say, it's always worked for me. Caetla also includes loads of rich functions like loading files from the PC, so you can emulate a disc and make your coding as large as you want. I wouldn't mind giving you a hand with getting started, add me on msn if you want Always willing to do some effort to try to resurrect the PS scene :smt043
Cool, nice one. My mate can code, I can't. But I can sit there all night drawing funky sprites and tiles. I'm trying to get his ass into gear and do a homebrew shmup. Not sure whether to go for DC or PS? I assumed PS would be easier? Anyways I still need to get him to actually do it. Oh well....
Indeed, the PSX is *very* easy to program even using assembly. The GPU is like OpenGL packed into silicon :-D Oh and SuperFunkyNinjawhatever, if you can't get your mate to code I might wanna give it a shot, doing something PSXdev in a team sounds pretty cool
