Re: Problems with Multitap.

There isn't a problem with the multitap library. The problem may be something in your code but my guess is the emulator is doing something wrong. Don't use emulators for testing. They are not accurate and none really emulated the multitap protocol correctly. You said it happens when you switch contr...

Re: SCPH-1000 - Sound issue

Could be an issue with the amplification circuit or even a faulty capacitor.

Re: SCPH-1000 - Sound issue

Nice SCPH-1000. Looks virtually brand new :) As for the SPU, press down on the known chips that process audio and see if it comes back. If it does, you've got a cold-joint. Flux up the pins with no-clean flux (I highly recommend CIF flux from France), use a bevel tip (also known as a single-flat tip...

Re: Inspiration For A New Game

They generally won't talk to you unless you have serious programming issues as they don't really wan't to waste their time discussing simple tasks that have been explained on the forums or are available in the Psy-Q samples directory within the SDK. Making a game like Driver or Crash Bandicoot isn't...

You've probably exceeded the 8.3 limit of filenames. Note that file paths are just limited to 8 characters.

Re: Recommend me a disassembler (or advice on making one)

But at the low level, 'noop' or 'nop' will always translate to the same opcode that the CPU can understand in binary. The assembler will always spit out the same machine code for MIPS so any decompiler will still understand it.

Re: Chip replacement.

It will work, but you'll need to match the pins of the modchip of the same carrier signal since if you follow a guide online for example showing you which pin solders where, it will most likely not work because each modchip is typically flashed with a different pin configuration in the PIC chip code...

Re: PSNee further development

Possible clock interference or interference in general from the modchip since that data (IE: the PlayStation logo) is pulled from the CD-ROM from sector 12.

CXD-2510Q would be your next option to check which is the CD-ROM DSP.

Re: Is it possible to develop an app that runs Namco System 11 ROMs onto a PS1?

It also has double VRAM. Anyway, in theory, yes, anything like this is possible but the system would need a lot of modifications since the System 12 is a custom board.

Re: PSX Physics

It can of course if coded correctly, but it would be slow. Also, there is no FPU so everything would be fixed point integer math. You can emulate the FPU in software, but again, it's slow so it wouldn't be a good idea.

Unirom is probably the best option at the moment.
I disagree. n00bROM is superior.

Re: How to load RSD Files

To load RSD you'll need to write some C code for the PlayStation to handle it. What the PSX does support is TMD which is converted from RSD. If I recall, TMD is just the object data from the RSD data, so it should be possible to do this in C on the PSX quite easily once you figure out the file offse...
