Re: How 3D on the 3DO really works... ?

Hi, I just want to try to explain the 3D rendering. First of all, you must forget current technology, the way 3D is done today has nothing to do with the early 90s. PSX, Saturn and 3DO were designed as what you would consider 2D render machines. Wait! I'm not crazy! :P we've all seen 3D games in tho...

Re: Things that can be improved

To tell the thruth the actual SDK seems easy enough to me, altough it's true I'm a bit oldschool :-P Anyway, creating a wrapper library sounds good. Currently I don't have too much free time, but if you need help in something specific I could help ;-) That's probably the first time i'm seeing a vide...

Re: LameNES (NES emulator) for 3DO ?

The github code is highly unoptimized, but I tried executing just the opcodes with no rendering at all and is still too slow, surely the 6502 core emulation can be done much better than the lamenes code, but I doubt it will be fast enough for the 3DO to render the frames at real time. And yeah, the ...

Re: LameNES (NES emulator) for 3DO ?

That emulator looks better but still I really doubt their 6502 emulation would be fast enough for 3DO. We're talking about an ARM60 13MHz with no cache that is shared with the OS and even stalled at times due to the DMA architecture (although I'm not sure how much time is lost when you don't have an...

Re: LameNES (NES emulator) for 3DO ?

I've noticed the color table is messed up :P About speed, currently the CPU_execute() call is taking too much time from the CPU, even if the rendering was super fast, there's no way for the poor 3DO cpu to emulate the nes cpu in enough time. lamenes does a simple switch statement, so we can try with...

Re: LameNES (NES emulator) for 3DO ?

edit: I've compiled your code and added the file streaming for 3DO and now it loads the rom.

I've noticed the code uses printf and that crashes the program, so you should comment those lines.

Now the problem is that looks like it's not rendering properly, but at least is executing the rom.

Re: LameNES (NES emulator) for 3DO ?

I've taken a quick look at lamenes sourcecode and the way it uses fopen I think you could just use 3DO's streaming file functions: Stream *OpenDiskStream( char *theName, int32 bSize ) int32 ReadDiskStream( Stream *theStream, char *buffer,int32 nBytes ) int32 SeekDiskStream( Stream *theStream, int32 ...

Sorry, didn't see this thread until now. In order to open a file, you must use File Folio calls, items and I/O system. You can get info in the official SDK documentation.

Re: Wolfenstein 3D Aarrghhh!

The 3DO port is currently my favourite, mostly because of the music, but also because all the new levels, better sprites and textures...

Jaguar port is also good, but to me it adds nothing to the original whereas the 3DO port is almost like a remaster.

If the cables and TV are already tested and ok, it can only be the video circuit as Aer Fixus has said. Are you using the composite output? Have you tried S-Video?

Re: The game that got canceled!

I remember playing disruptor and exhumed demos on my Playstation, they were cool for that time, it would be great to have them for 3DO. Exhumed was made for the Saturn, so it would probably be "easily" converted to 3DO, as both uses quad rendering.

Re: Did My 3DO Storage Method Damage It?

Maybe the laser needs to be adjusted. Have you tried if it can reproduce audio cds? If it works right then it's probably a matter of the lens intensity. If it can't read even audio cds, it could be also mechanical.

Any info on rom_tags generation?

So working with my iso tool I've come to the point in which I need to generate the rom_tags file. Thing is, I suppose it is based on the amiga romtags, but I don't know anything about it.

Does anybody knows this file is structure and how it is created?
