is a N64 emu possible on PS2???

[preacher]

Can the PS2 handle a N64 emu............if not why not!!:oops:

[Debby]

Well, the MIPS cpu of the N64 can be fully emulated on the PS2.
BUT the PS2 memory capacity is too small and slow to handle the N64 memory consumption.

I think most demos (you know what i mean if you used UltraHLE) can run smoothly on a PS2 - but who needs them :)

[BigGanja]

Well what about the HDD upgrade surely the ps2 with the right programming you should be able to use it as RAM memory in its own partition and BAM who knows maybe even Saturn and NEO-GEO emulation ??

[Debby]

Saturn and Neo-Geo emulation are very much possible on a PS2. You theoreticly right about the HD feature, but I can hardly imagine a programmer will spend so much hours on a project he won't get a penny from.
The only hope is if the UltraHLE sources will be altered to be compiled on the PS2-Linux, so the only overhead will be to modify the current sources .I don't see how the OpenGL lib used by the UltraHLE can be replaced by the PS2 version , but I'm not even an amature in emulator programming, so there might be a simple solution I don't aware of.

PS2 And N64 both used vector units, if that's any help.

[Abacabb00]

Man, if i knew how to code, i would glady try it. Where can you learn this stuff from?

[kylethesk8er123]

must be possible. look at the psp! almost full speed already!

[Z-Saber]

I'm sorry, but this is freaking five years old. Why the heck did you bump three separate N64 emu for PS2 threads only to add nothing of any value?

[Dangwoot]

okay here's the specs of both systems

if any programers out there can make any sense out of this it seems to me you'd be able to run a n64 emulator on a ps2 the only thing stopping you would be memory constraints.

[Shapyi]

The memory issue might be solved with developing a paging system with the HDD. Sure it would not be as fast as having the entire ROM in memory but if it is done correctly it could work out.

As for getting N64 emulated, that is probably a whole different story. An emulator would need to be written from scratch for PS2, similar to gpSP for PSP. Porting one would not get good performance right away because it would not have specialized code to take advantage of PS2's vector and floating point units.
