I just want to say thankyou for your hard work psmonkey. It may flicker a little but what i saw was pretty amazing and you have come a long way since the first screens I saw. Even then i was freaking out, i couldnt see the games in the pictures but i was happy that someone was at least trying to do it.
Jesus christ. Talk about down time. :P
Anyways I've been busy with work so not much progress.
I did how ever fix a small bug that makes quest64 even better. It was really ignorance on my part. I needed to turn backface culling to Counter ClockWise (which is what f3dex microcode used) and that pretty much solved alot.
I fixed some PI DMA Bugs & also There are some recent improvements in weltris which now shows some of the 3d menu but crashes in game. Not sure why it crashes yet.
I'll get some shots up later today.
Well thats about it for now. :P
Ah good to know, yeah it was a very long downtime. Good thing stuff seem back now.
oh yeah. Here I've been meaning to add this in but been a bit lazy.
Now Monkey suports full screen. :D :D
The game is a bit streached not because it's streaching a 320x240 image to full screen. It's insted modifying the viewport to fullscreen. So the 3d is still drawn in a [-1,1] format but now -1 = 0 and 1 = 480.
:P
--edit--
The black lines are from printf (not because of emulation. :P)
nice screenshot
Ok heres another for your viewing pleasure :)
wow. seems to be comming together great.
Looks great, monkey. You've done far more than most people expected and in such a short period of time.
Kudos to you.
10 fps?? nice 1
Nice but why does it look better on the movie??
Is it because its moving???
Mostly yeah. A movie does make it better since you can get a sense of how fast it's running.
screens look nice monkey!
any progress on iris?
HFS!!
Thats freaken awsome!
btw, has the speed gone up at all?
Wow, that downtime bugged me out bad.
Me too...for a second there I was worrying that you were given a cease-and-desist...but then you'd think the site would still be up.
:eek: Those are some nice screen shots! Monkey 64 has come along way since the white boxes in Mortal Kombat Trilogies. BTW how does that game play now?
game is about the same. My shot has a low fps because of constantly trying to take a decent screenshot (and it kept sending me to the pause menu). Quest at the moment is around 11-14fps in the start of the game. Not sure how it is later on. never tried that far.
--edit--
the fps is low from screenshots since dumping vram to a bmp takes a few seconds which causes for the next update of the fps counter to be inacurate. As well my fps updates are not very frequent so it takes a few seconds to update the fps counter.
Good job ps monkey that is a huge improvement since march. GJ!!! :)
So instead of stretching to full screen cant u just make it display full screen normally?
Ok not much progress. I spent last night debuging mario again. I found out it has some serious pi dma transfers. This is bad and what is posibly breaking the game. So i am gonna dig into it some more today.
Actualy it is. When the psp recieves the polygons. It's rendering them to the psp res. That is why it looks better then a 320x240 image streached full screen.Quote:

Hey Monkey could you give me a little rundown on what pi dma transfers are (assuming you have time, since you are a busy person).
When you say this is bad do you mean in relivence to Monkey64s possible development, or simply another obsticle that will take time to get through?
Would be a shame to lose Nintendo roms. Anyways keep up the good work and thanks for your time!
Just a difficult thing to get though is all.Quote:

Mario64 does a bunch of transfers properly but 3 specific transfers become invalid. I am not sure if it's with in the block of code that made it invalid or if it was invalid before being passed to the block of code.
It's not really complex but I need more time to probe for the bug.
Thanks for the explaination!
Well I guess half the solution is finding the problem. Good luck, and keep us posted!
Wow! This is turning out to be awesome! Any idea on when you think Mario Kart 64 will be working?
Jus a question PSmonkey, i admire how you dont get demmoralised when you get stuck with a bug with ANY of your programming, how do u keep going?
I'm wondering that myself...I've taken several hours in my coding (and I'm coding much simpler things) trying to fix little nitpicky bugs, and after all's said and done, I usually give up for a couple of weeks at a time. How do you manage?
The love of the "game" no pun intended...
everyone has their passions.
I go all ninja/comando style on the bug. Running at it full force and testing all angles till i drop dead of sleep deprivation. :P
Somehow, commando style doesn't fit in that sentence.Quote:

So far I've traced it back to a tlb instruction. I think I went far back enough to find the different memory addresses for the different loads.
It goes (best i can figure out)
ERET (not sure why, I might have this wrong)
Increase Stack pointer
Store registers to stack
Load branch addr (the start of our function)
Load Addr for PI values <- Different after first 20 transfers
Load RDRAM_ADDR to A2
Load ROM_ADDR to A1
Load WR_LEN to A3
Branch to Addr (Loc for pif transfer)
Increase Stack Pointer
Store Registers to stack
Do Some Work
Load RDRAM_ADDR from Stack
Translate RDRAM ADDR
Store RDRAM_ADDR to PI_RDRAM_ADDR Reg
Load ROM_ADDR
TRanslate ROM_ADDR
Store ROM_ADDR to PI_ROM_ADDR
Load WR_LEN
Add -1 (odd it does this vs calling sub instruction)
Store WR_LEN to PI_WR_LEN
PI_DMA_WRITE triggered by previous instruction
...
...
Branch ...
... = Cleanup but I am not fully sure.
That is what I figured out so far in a nut shell. Atleast now I have an addr for where it gets the values from. So with more tracing. I can find out hopefuly what is writing to that specific address.
:( Hopefuly mario will be going soon. I dont want to have to reverse enginear the entire game in asm just to find the bug. :P
Ah yeah, interesting... I figured you were doing something similar thought.
Do you have a special debug mode in your PSP version, or like you write in a log file or you just check which block code you are at ?
I have it setup now where I can make debug builds that give me more options (like break or debug at an addr, then either wait for input or just start printing the opcode list from that point). It helps in debuging.Quote:

haha just leave him alone man, as u can see he is really busy with Monkey 64 and with his personal life.
heh, i was kidding.. i remember at one point people were giving him an aneurysm over a halflife port HE SAID HE WOULD NOT DO!
Psmonkey, this is just getting better and better. I am just dying for the next release,(do you think you might release the next version when are able to get mario to load correctly?)
hey psmonkey do u think it would be possible to release by the end of the month? it would be pretty cool to check it out in its current state. maybe we can also find new bugs.
When Mario 64 runs everyone's gonna be playing their PSP like crazy. I hope Mario runs soon.
I think Psmonkey will have Super Mario 64 somewhat working by E3 :)
I dont care what mario gives me. If it gives me anything even just playing with the freaking 3d head. I'm posting a build that same day it works.
No clue when that is.
Runs after 1timeuser samurai style with a nerf bat.Quote:
