Re: Ridge Racer Revolution 3D Models

Look for 3D Model Researcher on Google. But first you need to extract the data from the game's archives, for this a hex editor for research and some basic programming will do the job, C, Python, anything you're comfortable with.

Usually game archives have table of content in them with offsets and ...

I just tested it on my side, no issues in Windows 11.

Re: NO$PSX V2.2 Released (16th Dec 2022)


Is this a bug? Here's how lines appear in NO$PSX compared to other emulators. Lines where (x1-x0)>(y1-y0) become dots. Test program attached.

NO$PSX always had this issue, I first noticed it years ago in Vagrant Story.

In general I don't expect accuracy from this emulator ...

Re: Decompilation of n64 games, what would that mean for PS1?

Even though N64 can do floating point calculations its RSP coprocessor operates on fixed point math for geometry transformations. But the biggest challenge here is to rewrite the code for PS1's GPU, reduce memory requirement and implement data streaming from CD. Many other roadblocks may occur in ...

They are very common on NDS, they are also common on PS1 and sometimes even on PS2. I didn't have much experience with N64 binaries but it's probably not an exception either.

Re: Question about NO$GBA

Forgot to add something. Execution breakpoints become useless if a game loads an overlay to the area where they were set. This basically makes it hard to catch a code execution and forces the user to constantly monitor memory changes in order to update each affected breakpoint if needed. This ...

Question about NO$GBA

Is there a hotkey for switching between ARM and Thumb in the disassembly window?

I can't find anything related to it in the provided help documentation. The lack of this function drives me nuts because currently I repeatedly switch between game and disassembler until it lands on Thumb code in the ...

Re: mp3 decoding

I think, people on https://www.vogons.org/ would like to test this thing on an old hardware, but I'm not even registered there and I don't have such hardware.

I tested it with a few tracks on my PC and sometimes they just stop abruptly at random points while the program keeps running and never ...

Very often games use their own image formats which are similar to TIM in nature but have totally different header and sometimes they use compression for them, more to that, some games use texture atlases for faster loading, so they just load entire texture pages at once including CLUTs packed in ...

Re: ADSR Behavior Consensus?

Tried this tool in some emulators:
Xebra - seems like this emulator is unable to read the needed data from SPU so it just shows straight lines.
Mednafen - this emulator often hates anything that is not a commercially released game, so it refuses to load the EXE file and shows its bullshit message ...
