Re: Problem starting external PSX-EXE

Something is getting trashed in memory then. You'll have to do some more debugging and tests. One thing you can check is to compare the registers on the one that works and the one that does not to make sure that something like RA (for example) isn't pointing to something different.

Re: Problem starting external PSX-EXE

Try doing it with interrupts disabled by using 'EnterCriticalSection' and then turn them back on with 'ExitCriticalSection'.

Re: Trying to read the TIM file.

No, you can't use an unsigned long like that. You'd have to use a char. You can use u_long *TIMLogo; but point it to an empty place in memory by doing u_long TIMLogo = 0x80010000; (correct that address if need be). You'll have to make your own malloc routines to assist with dynamic memory management...

Re: Trying to read the TIM file.

Turn on compiler warnings. You're missing a closing bracket at the end of the first statement. TIMLogo should be hopefully defined as an unsigned long pointer (you should use malloc for better memory management but that can be worked in later if need be). Don't use nbyte. Use &fp.size (but it must b...

Someone was already making the PSX on an FPGA core. There was a guy from Japan doing it. Run a Google search and you'll find him :)

I tried to modify the DISPENV parameters, of course. It didn't work so well.
So, the only way to do that, is making the screenshot of the display to VRAM. But still, how they're do that?
StoreImage and LoadImage.

Thanks, it's working much better than the _boot command.
Yeah, I'm not sure why _boot doesn't work. It might be worth dissembling the library to see what it's doing.

Yeah, it's bugged I think. Don't use it. Just jump directly to the BIOS address instead.

Edit "PSYQ.INI" in the BIN directory and make sure the library (libsio.lib) is defined.

Re: New Member: Logan Jones

Nice work! Appreciated. I can confirm that both dumps are the same (the CRC32's are identical). Now you can re-flash the cartridge with whatever ROM you want without worrying about losing the original ROM it came with :)

Looks like V4.52 since it's in German, but have a look to make sure! Do the steps 'Squaresoft74' mentioned to change the video mode :)

Re: New Member: Logan Jones

There's a list somewhere here on the forums. Best to use the 'Search' function to try and find it :) A FCD (Future Console Devices) file was (if I recall) a way to encode the ROM to stop people tampering with it, but obviously it wasn't secure and was cracked easily which is why there is a decode op...

Hold on a sec. How do I connect my PS1 to my PC's serial port? Is there like a common and cheap adapter I can buy?
You need to build a cable or buy one from I think 'danhans42' on the forums.

When you power on your Xplorer FX, just take a photo of the menu since the version number is usually placed there.

Re: New Member: Logan Jones

1) Not sure, either should work but probably the NO$PSX kernel clone since it's more up to date (UNIROM hasn't been updated in years). 2) No, you shouldn't have to. 3) If you did, you'd have to hex edit your file (just re-inject the same binary twice and re-save it as a new one). 4) Yes. Even if you...

Re: Easiest way to make a Sprite?

The CLUT is contained within the TIM file itself. I can't remember the format of a TIM exactly (it's been a while since I last checked it), but if I recall, there is a header, the CLUT and then the image data itself. There are heaps of Sony examples on how to use 4-bit or 8-bit TIM images. EDIT: Ah,...
