Zilmar is a god among monkeys !!

Monkey Present :D

Thanks to zilmar's help (of PJ64). I have fixed a few stupid mistakes I made in opcodes and starting register values (lol, n64 though it was in pal mode).

Anyways many more demos are now running but more bugs are stoping me further (most demos run 1-2 frames then hang or need more opcodes emulated).

So enjoy the shots and good times all around !!

Nice Progress

It's nice to see you makings such great progress, and it's really cool to see that other N64 programmers are willing to help you out.

Keep up the nice work, I'm really looking forward to Mario 64 one day.

P.S. I remember reading in one of your previous posts that you hope to run Mario 64 at 30 fps. Was 30 fps. its original frame rate?

Small update.

I fixed my lock up bug today on fire demo. It now finaly keeps updating. Along with this fix Fire Demo now works & so does Pong by Omar. Yet there are some bugs still in others (absolute crap 1 & 2 still hang after a few cycles, pong input is bad ( left trigger sent my pad up and that was it. :P ) ).

anyways a more proper anoucement will come later in the day. its 3am now and i need to get some rest. :)

hi psmonkey will the emu play banjo-tooie and dk 64 oh yeah by the way good work
February 23rd, 2006, 15:24
PSmonkey

sweet i have a fanboy now (m64fan). :P

well after being up so late last night I dont want to get up this morning. :(
I made a typo in my last post. I ment I fixed a bug for n64 stars (not fire demo) but that same bug was what locked up other demos from working. Either way. YAY.

With more and more things starting to work (including new demos) I am starting to debate a time frame for release. I was originaly gunning for "when more runs, post quickly" but I am thinking not to do that. I am actualy thinking of trying to get the emulator to the point where it's waiting on rsp emulation. That way when I start on it again (need break to work on iris) I will be starting in on rsp emulation to start running comercial roms. Sure it might only take me another week to get to this point but I am thinking of delaying it further for a huge release on march 9th (there be a reason for that) but I am unsure atm. So I will have to debate it further and also continue to hunt down bugs.

Well anyways i'll post some pictures up later today of new status & of me hopfuly kicking the n64 ass in pong by omar. :D

Untill then. *chimes ghostbuster music* There is something strange in the coding base, who you gonna call? Bugbuster!! It doe something wierred and it dont look good, who you gonna call? Bugbuster!!

m64fan,
It will be a long time till banjo-tooie or dk64 work. The reason being is they are larger then 16MB which is my current limit for the emulator. I am thinking to get this fixed after some time but the result wont happen till after mario64 is running & after the recompiler is implemented.

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?
February 23rd, 2006, 19:31

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!
February 23rd, 2006, 19:51

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?
February 23rd, 2006, 21:29
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....
February 23rd, 2006, 22:04
Wally

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 )

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.

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.

Psmonkey, would the available memory be an issue on 2.00+ ? (I have a 2.0 thankfully :p ) Because I think that all the memory (24 mb I believe) is available in User Mode. And because the new Eloader has freed up more memory. I personally think the memory would not be an issue anymore, but I am not sure. So what would be the benefit of having a 1.5 over a 2.0 on Monkey 64? Would there be a difference in performance, or other functions? :confused:

Thanks :D
February 24th, 2006, 11:47
crazyjohn

Im pretty sure there are issues with running power hungry apps on eboot loaders because they dont allow direct access to all memory and hardware functions. Also (and im not saying this will happen) if any of the proccessing was moved to the media engine for optimisation purposes anything beyond 1.5 would be ruled out. Basically, if you want speed and functionality, stick with lower firmware.

(Waits for PSMonkey to answer and tell me if ive got the right idea or im way off)

Yes , how could i be so stupid! It was the snes!
Well that's a relief becouse i love starfox.
Thanx for the correction PSmonkey, nice to have you in the discussion.

One of my favourite games ever is Blast Corps on the N64, if I could play that on my PSP I'd be in Heaven!

Well thanks for the information I appreciate it. And also I do own the original n64 system but what I was thinking from a n64 emulator on the PSP was it would be the first hand held n64 (emulation). So that is why I was wondering how you would be able to run the emulator. Also I was looking at the specs and to me I could be wrong but it did not seem as if the emulation was very possible but I'll take your word for it. Well good luck!

Unlikely (it be a miracle if Mario64 works) and not anytime soon (think months [wild guess 6] ) for a version running commerical roms nicely.

PSmonkey

but dont forget the break i must take on monkey so i can work on iris for the dcemu compo that ends in april (i have alot on my plate for that).

Yet I think in another month of work we can see comercial roms booting. Maybe mario playable in 2 months and 4-5 months for a solid recompiler so we can get playable speed.

Few things to take into consideration. with a little trickery (like when roms are waiting for a vsycn to accure) a few fps can be obtain. Like Chaos demo runs at 12.5 fps vs the 5.5 that fire runs. Why? Well because chaos goes into a little opcode loop till a vblank occures. Since we speed up emulation when this happens it gets a bit higher frame rate. I currently only do this on the J opcode but if I add it into others we might see a little boost in others. :D
