Re: Newbie wanting help

First I would suggest to just go with 16 bit images to avoid using CLUTs. Once you manage that then start using palletized images. You should upload image to VRAM outside of your display buffer (usually 320,0 should suffice) and then make a sprite out of it. After that set up a game loop and draw th...

Re: Newbie wanting help

You can place CLUT anywhere in the VRAM. I'm not sure I understand when you say that it will all be filled up... As for displaying text you can use FntPrint() function. printf is for debug only and is usually used on serial port.. However I encurage you to write your own text displaying routine beca...

Re: PSX CD-Player only Project

Shouldn't be difficult. Take a look at the sio echo example in the SDK.

You can check each game loop if there is a character waiting in the RX buffer and execute
a function based on the value.

There is also a SIO interrupt available but for simple stuff like this it's not necessary to set it up.

Re: New cord to Playstation controller ?

I suggest you go with some other cable. I replaced one of the broken cords with CAT 5 and it is a bit too stiff. I think 8 wire shielded alarm cable would be perfect for the job. And replace the whole cable (not just from the ferrite bead to controller). If you look at the front side of connector yo...

Re: PSOne development kit

It's possible since it's basically the same machine (with a few subtle differences) in a smaller form factor. Yaroze has a different mechacon then retail units which allows you to boot software from all region plus yaroze discs. That can be solved by installing a modchip, either MM3 for SCPH-101 or ...

Re: Super GameBoy like for PS1 !

Funny. I always thought there would be more to it than what the cart contains... I have an idea though. If that cart only places PSX-EXE and GB ROM into RAM then after a reset it should still stay in memory. I could modify my BIOS dumper to dump any part of the RAM to serial port and use BIOSGet to ...

Re: Hack PSX-USB dual adapter due to max current limitations

Don't forget that connector has two vcc pins, a 3.3 V one and 7.6 one.
That's probably why your controller works but it has no rumble.

Re: Arduino Memory Card reader

Adapted? No. Because this simulates a PS1 side of thing and acts as a SPI host. However if written from the scratch it should be doable. The first problem with this I see is that you need a device that acts both as a SPI slave (for Memory Card) and SPI master (for SD card). So, maybe some other micr...

Re: PS1 Sound Trouble

You will have to open it up and see how it looks on the inside. There could be corrosion. For many people nowadays PS1 just takes space so they toss it in some storage (attic, basement, shed, etc) and there could be moisture. I bought one which was so bad that nothing (except plastic case) could be ...

Re: Return to the PSXSERIAL loader without resetting the PSX

You probably need a slightly different syntax.
The code i posted above compiles fine with the MIPS configured GCC core toolchain I'm using (PSXSDK).

Try with this:

Code: Select all

.global WarmBoot

WarmBoot:

Re: MultiMode3 Source

Are you talking about PSone when you say PS1? Because PS1 means all PlayStation 1 models (fat and slim). Yes, MM3 works on PSone but if you are using it with a PAL console you won't be able to boot NTSC titles without a boot disc. That's because an extra check in BIOS was added to those models. To b...

Re: PS1CardLink - help with cable needed

Do you have a multimeter? Check continuity from adapter to the end of the serial cable. Also make sure that you actually connect to TX and RX lines on a cable. And leave CTS - DTR connected at all times. BTW: BIOS and games won't print debug info even if your cable is working properly because serial...
