WOW, great work! I can't wait to play mario 64 or super smash bros. Keep up this amazing work! By the way, I just got a 2gb memory stick pro duo so I will be able to put tons of N64 games on my psp! Also, about when do you think that Mario 64 will be running along with other commercial N64 games?

You'd better don't ask developers for release dates, that's a source of stress!

16 mb let's see.......... Goldeneye, blastcorps, mario64, pilotwings, waverace, diddykong racing, mariokart, tony hawk, micro machines, banjo kazooi, fzero, mage the dark age, yoshis story and about 30 more roms in my collection wich are 16mb or less! Wow! Well i'd say that the 16mb barrier is not a big problem at all becouse most of my (and allmost everybody's) favorite titles are within this limit! You are really a hero psmonkey, thanx for working day and night on this!

Hey guys, don't jump the gun.

He said commercial roms won't work cause he still needs to implement rsp emulation. So for now, only PD roms. Get your N64 versions of Tetris and Pong out and be ready to play

You forgot Zelda, It is way over the 16 mb barrier unfortunately . I am sure that is also one of everyone's favorite titles. Cause then again, who doesn't like Zelda?

[Knutselmaaster]

Yes i know, no zelda, but i was only naming titles with less than 16mb, and starfox won't work neither although it's under the 16mb barrier witch isn't working becouse of the required fx chip emulation witch is hard to accomplish....

There has to be a way to make zelda smaller without killing the game in anyway.

I will do some research but im not promising anyone anything

wrong version dude. Starfox snes used the fx chip. starfox 64 used the normal n64 hardware and is posible to emulate (its actualy another mario64, not heavly demanding on the hardware )

good luck dude you know you have my support. Need anything just ask.

By the way don't answer this question if you really can't justify it. And for the fact i don't want to stress you out. But even if you get commercial games like Mario 64 running do you think you will ever get a good emulation for the speed. Cause even though we would all be impressed seeing it play. The truth is we want to play it. Just a question. Cause I don't want this to end up like the ps1 project. cause that project almost seemed like a complete waste of time. (No disrespect in any way, just trying to see where we stand).

It sure seems like it.

I feel your post needs to be addressed on a technical level so please bare with me.

As some have already pointed out, the PSP & n64 are mips processors which share alot of simularities. The instruction set on both are relativly close and with both being mips processors instruction layout will be about the same as well. In other words an ADD V0, V1, V2 is going to be the same on both.

Pc use x86 processors wich are cisc in design (unlike the mips which is Risc). So there is a vast amount of things that are different. What has caused for some really good speeds on the pc is emulators implementing a dynamic or static recompiler of the instruction set. This is yet to be implemented on Monkey 64 which at the moment is only interpreter based (which is ungodly slow mind you). The n64 emus for xbox are not very good or well optimised compaired to many pc n64 emulators (wich is rather sad since it should have been straight forward to get one going on the n64).

A few additional things that are interesting about the n64 is that it's registers are 64bit. While this sounds daunting for a 32bit system to handle, most instructions on the n64 mips processor were actualy 32bit with additional instructions added on to handle 64bit arithmatic. Thies instructions are not as heavly used as one would be led to believe. On top of it, mario64 & many other early n64 games did not push the system a whole lot, Alot of the geometry was rather basic, Rsp & Rdp were not worked to the bone & in most n64 emus for pc, mario 64 is one of the n64 games to actualy run almost near perfectly.

So is 30+ fps posible? Actualy its more posible then lead to believe. I have had numerious discussions with a few well known people from the n64 emulation & development scene. Both know the n64 like the back of their hand & feel that n64 emulation on the psp is quite posible if properly writen.

So how do I plan to properly write a n64 emu for the psp? By recompiling the mips instructions to psp mips instructions. Since both are simular very, less work will be needed to make this accurate compaired to recompiled instructions for a pc emu. I plan to recompile cpu & cop0 instructions to the main cpu. Cop1 instructions (floating point instructions) can be recompiled to take use of the psp's VFPU which also have their own set of registers. This will help out emencly in emulation speed.

Well thats about it. Do take into consideration that on the revolution, you're going to be paying out the teeth to play classic n64 games on the system, on top of it you will only get to play what nintendo provides. If you want to play games the way they were ment to be played, then buy the original system then. Thats the only way you will get to play things the way they are ment to be played.
