Re: OperaFS[De]Compiler commandline or source code?

This is kinda old thread to reply, but I've been recently looking at this too. I was using OperaFS and a tool called autohotkey that automatically does timed keystrokes to select compile, type the cd directory, and tab through the buttons to press and do the process. This was setup by someone else h...

Here is the final of this project with demo and benchmark options https://www.youtube.com/watch?v=VIVCz_LJEB0 And here is an emulator capture of the demo (because I don't have capture equipment for real 3DO and it looks not blurry and smooth here). https://www.youtube.com/watch?v=ISIXplL57yo Downloa...

Re: New demo (STNICCC 2000 animation)

An interesting conversion of this project to a texture mapping benchmark. Might release it soon, after I fix few more final things. https://www.youtube.com/watch?v=XI7Cph4678A looks sweet.

Re: Suggestions for open source projects

Thanks for the list. Rick Dangerous seems interesting to port (and maybe much easier and smaller game than the rest). I was thinking to look at some old homebrew or open source games (even from GP32 communities or some old DOS stuff), maybe there are few that are not hard to port. Even if a game on ...

Re: Gameblabla's Crappy Compilation

I noticed back in time that it didn't work and from what I heard, the original author doesn't have a real 3DO. From my recent experience, it's quite easy with certain code in the C compiler I use to make it just freeze in real 3DO but work properly in all emulators. Simple things like non aligned 32...

Re: Help compiling iso

If you are in windows you can make a batch file (for example encrypt.bat)
which you open with a text editor and type the single line and save:
3doEncrypt.exe genromtags file.iso
You will need to have the 3doEncrypt.exe tool of course at the same folder as the iso.

Re: [Tutorial] Compile your first 3DO game

It's a shame some files are gone. I also was looking for them.
I had released an example project with all the tools and batch files for the process, I hope it can be useful.
It's good to see other people want to code for 3DO.

Yes me too, I just did a big level with many enemies, either reject or not, mine doesn't slow down.

I think I might try to compile your code and use your rez to see what's going on.

If you want to change the flushing value, at threedo.c there is #define CCBTotal 0x200. I have managed to set it to something like 0x1000 and still fits in memory. I also managed to count the CCBs per frame by increasing a counter in every function that adds ccbs, and it can go from 240 to 1500 in w...
