Lol, just a turn of phrase; figured it would translate to Aussie English :p

But yeah, if it's no hassle, it'd be pretty awesome to see any others you've found ^^

Re: How to dump your CDROM BIOS (Firmware)

Ah, no, not me. I am an ASM programmer. I am not doing HLL stuff, never, no chance. I am now certain that you're a lovable eccentric. Got me thinking about the differences between the PS1/PS2 though. Every few revisions on the PS1, you'd have to use slightly different disk swap timing... (going som...

ASM Demo: Magical Assmbler Spooky Ectoplasmic Gloop Gasm

50 Ahoyhoy I haven't done much PSX-related recently, and got the craving for a little assembly. I kinda wanted to finish off ROMProd's upload/download feature, but don't have a working parallel port, so I've been doing this for a few days. Bliss =) Not sure I'll get around to finishing it, but it w...

Cheers - I didn't realise he'd released the PC end of things for this - I already have the PSX code intergrated into RomProd, so this should be awesome :)

Re: Custom ROM creation issues.

Just a little project update: -Got pad input working pretty nicely -Menu options! Circle to return to BIOS for example, Triangle to boot xFlash or *.exe -Got a bit of a gui up and running, just some lines and gouraud shaded quads -Got some sprites working (as above, needs to be copied to RAM) -Sprit...

Re: MIPS R3000 Instruction Set and Advanced Machine Document

Thanks man, nice list - here are a few I found pretty useful:
http://www.cs.umd.edu/class/sum2003/cmsc311/Notes/ (Scroll to mips section, there's a pretty good introduction)
http://en.wikipedia.org/wiki/MIPS_architecture (seems kinda obvious, but the assembly section is invaluable)

Re: Custom ROM creation issues.

Lol, might be a good way to get some use out of my pile of gameshark clones - I don't have a serial cable or anything though :( Guess I could just use an Arduino? I'll think of something amusing to do :D

Re: PSX CD-Player only Project

Cool, very helpful - thanks :) Only took a bit of patching (register names, explicitly loading the jump table), but it boots perfectly now! I initially thought it was something SPU relted as some demos like Sadtro would still run but lag like the SPU was causing some kinda blocking. I suppose it's p...

Re: Custom ROM creation issues.

Excuse the double post, but this is feeling like a work log. Just a little release - like RunRom, but you don't (always) need a disc to boot. Some .EXE will work just fine off the bat, some need a little wiggle of the switch and some just take a bloody long time, but hey, it's coming together. http:...

ROMProd - Run .EXEs from XPlorer rom. (0.2)

Edit: Update 0.2 - Proper booting without the switch toggle. Ahoyhoy, It's just like RunRom, except now we have a source to play with. In truth, much of it is patched together from other peoples' bits n pieces, but they're duly credited. Still, not too shabby for my first 'thing' in r3000 ASM. It ca...

Re: Custom ROM creation issues.

Hehe, yeah I found some old pinout diagrams, but uhmm... when they started producing the FX carts they cut a few corners. The new EEPROM for example isn't a regular chip with .1 inch pin spacing, it's one of those little fellers, sort of smushed in the middle of where the old chip was, with extra li...

X-Killer 0.55 Patched

Just a tiny little patch for X-Killer 0.55 that allows you to upload 512k non-FCD roms to the XFX. It's not generally an issue, but handy if you wanna append some code,image,music, etc to the end of an existing rom, or to mess around with MultiRom (which uses 2 x 256k banks regardless of original RO...

Re: Custom ROM creation issues.

Heh, I've always had a fascination with ASM being so close to the machine. 10 years ago or so I would have been all over PsyQ if I could find it anywhere, but suddenly it seems like it's not what I was craving. I've found some pretty cool things already. For example, did you know that a jumping to 0...
