@Shadow: But your TV was originally supporting 15 kHz hsync ?
Yes, well 14.4 KHz to be exact (according to my old scope) but it's most likely 15 KHz :)

Re: mkpsxiso help

It seems the OP wants to make an image. If you want to add XA and/or CDDA this is where things become more difficult and where BUILDCD.EXE or MKPSXISO.EXE are extremely useful :)

I myself never had luck with CDDA and BUILDCD.EXE so I always use LameGuy64's program to do that :praise

Re: mkpsxiso help

Make your *.XML file and then use these arguments. Obviously, rename 'example' to whatever your sheet is called.

Code: Select all

mkpsxiso.exe -y example.xml

Re: mkpsxiso help

Don't double-click the executable. You need to execute it from within a command prompt with arguments.

Re: psyq2elf - Convert Psy-Q SDK libraries

That's really nice work! Would be very interesting to see a modern GCC compilers binary output and compare the assembly with the CCPSX compiler to see if it optimises better.

Re: Black PlayStation ? (versus PSXSERIAL)

To be honest, I'm not sure if the BIOS for those consoles did that. Someone will need to confirm (just need to dissemble the BIOS and compare it with a retail BIOS). Really though, all you need in your code is AddSIO(9600); and it'll then redirect the TTY from parallel to serial. Another way to test...

Re: Reverse Engineering the PSX Copy Protection (Wobble Groove)

What you've read is probably demodulated already. In order to re-master the wobble on a CD-R, a burner needs to write it at a 22KHz frequency.

Re: Reverse Engineering the PSX Copy Protection (Wobble Groove)

My original experiment was that burning the wobble right after the ATIP on a CD-R might cause the PSX tracking servo to lock-on and track that injected 22KHz wobble. It's all just theory though and an experiment I was interested to try which is why I wanted to scan the physical wobble pits and lands...

Re: Not getting CD-DA to work...

I've found that the CDDA mastering process by CDGEN and BUILDCD don't work for me either and I couldn't ever figure out why. XA was no problem, but I always had issues with CDDA. What I found that worked in the end was using LameGuy64's MKPSXISO program. If you use this instead, CDDA plays and works...

Re: Reverse Engineering the PSX Copy Protection (Wobble Groove)

'Hack a Day' took some of the information from this topic (including those audio recordings I posted). 'Modern Vintage Gamer' seems to have got the majority of his sources from 'Alien^PDX' (that's Alien of Paradox, a long time member of Paradox). I genuinely believe it is not possible to burn a wobb...

Re: MKPSXISO - A PlayStation ISO Maker to Replace BUILDCD

That Yaroze file has already been combined (the header already contains "COMBINE version 1.00"). So, just rename it to MAIN.EXE and master it to a BIN file. The PlayStation (including PSIO) will boot it (even without a SYSTEM.CNF sheet). If you can't do it, I'll do it for you. Just let me know.

Re: PCinit causes black screen

For emulators, compiling an ISO every time is fine because it's extremely quick. If you're on a real PlayStation it's a nightmare because you need to waste and burn disc after disc so that's when PCinit(); comes in handy for quick data transfers to the PSX memory :)

Re: This disk does not have raw headers Audio may not be detecte

I think I have the source code to PSX2HD, but it's been a long time. I might only have the binary for it. If you can upload it that would be useful so we can keep it archived.

Re: PCinit causes black screen

It won't work with ePSXe. You need to use real development hardware (DTL-H2000, CAETLA, CATFLAP, etc).

Re: Need a guide or a fully walkthru on how to modify/rebuild psx games

You can use an Xplorer and find memory changes to then lock or change the values, but the proper way is to find the function in the code by disassembling the machine code from the game and alter it. You need to know MIPS in order to do this and how the PSX CPU works, so this is why there are no 'gui...
