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...

Read the documentation. It explains what one of the key issues is when programming it :)

For creating temporary assembled and output files as the compiler processes up until the linking stage.

Re: MIPS R3000 Instruction Set and Advanced Machine Documents

Just run "ASMPSX.EXE" and it will list the switches.
  • m+/- enable/disable macro instructions
  • l<char> make <char> the local label character (not + or -)
  • c-/+ case sensitivity

Re: Programming a Loading Screen? (Not a Background)

You got a lot of learning and looking at example codes ahead of you. Use the forums to search and find programs already written or look at the examples in the 'Homebrew' section on the website. Use a VSync callback to display what is being loaded or to show a loading bar. LibDS is quicker then LibCD...

Re: Can't Read SN.INI or PSYQ.INI Files?

Pretty sure that CCPSX looks for
  • PATH
  • PSX_PATH
  • LIBRARY_PATH
  • C_PLUS_INCLUDE_PATH
  • C_INCLUDE_PATH
  • PSYQ_PATH

Re: PS1 for sale with PSIO module. Play games from SD card!

If you sell it make sure you provide the buyer with the email address and Order ID from the purchase so they can get updates. Cybdyn Systems requires that to download firmwares.

Re: Can't Read SN.INI or PSYQ.INI Files?

CCPSX will look for them in the path directories specified. Usually they should point to C:\PSYQ\BIN where those two files would be located.

The clones are not cheaper and they cannot be updated. Not worth it at all :lol:

Re: chipped PS1 and PS2 consoles for sale via minifree.org

No one really uses modchips on PS1's anymore. Everyone uses PSIO these days. The dual-oscillator mod is very useful though when not using RGB :)

Re: CRT RGB Modification/Hack [56K Warning]

Okay, I am totally incorrect. I hooked up the signal generator and it is not the frequency which drives the contrast/brightness. It is in fact the amplitude of the signal. So, I'll need to build an amplification circuit which takes RGB in and feeds a higher amplitude out for each channel (IE: red, g...

It might not be compatible with that type of cartridge.
Even if the EEPROM is detected?
Yes, because it could be detecting the incorrect one.

Re: CRT RGB Modification/Hack [56K Warning]

Okay, 5 years later (03/FEB/2020) and I was looking into this again and doing some thinking (because I want to finish the TV off), and it seems I need to build a "frequency doubler" or "frequency multiplier" circuit. The problem isn't the voltage levels because the transistors will 'turn on' at even...

Yes, it uses the old GPU with VRAM (not SGRAM).
