Yes sorry you are right, it is executed (jump destination computed) first, but the jump is not actually taken until after another instruction is executed. Just making sure to point this out because it's a pretty alien concept for x86 people :)

SELECT + L1 = L2
SELECT + R1 = R2
Would be nice

AND
SELECT + ANALOG STICK = Second analog stick..

and pushing select button for 1 second without pushing something else then it would be a just SELECT

if you didn't get my PM then I think we can work together and get this working fast. I have some ideas so AIM me at thehalo2renegade

For all the people who have been asking, here's the first demo test release of PSPSOne. This one is hard-coded to run the pdx-dlcm.psx demo, but I've included a few other psx files as well. It runs at about .5 fps @ 222mhz, The emulation is really slow at this point, I'm still working on getting my recompiler to function properly (or at all). Once the recompiler is working, I expect to see a huge jump in performance. After that, I'll replace the GPU software rendering with the GE calls to hardware blit 2d triangles.

You'll need to run the KXploit tool on this. The directory must be PSPSONE, Also, you'll need to put in the scph1001.bin playstion bios into the /bios subdirectory for this to work.

I know it's really slow, but it's a start.

good work PacManFan hopefully after some polishing this will be able to run really fast and have a good library of games that work.

PacManFan check your PM box. Also I think a playable version might not be as far off as we think.

I have a suggestion for controls have the analog stick be the l2 and r2 buttons:
ei moving the analog stick left would be L2 right would be R2 up could be L2&R2 (if you have to press both) and down could be the menu.

Mike/Pippin · Joined: 05 Jun 2005 Posts: 40

easyer would be

R2=R1+/\
L2=L1+Up

Theyre close and easy to do.

im **attempting** to run it on a 1.5 version firmware(using kxploit as well as the seipsptool(same thing only it lets you hide the "corrupted file") anyway, Very new to the scene, trying to learn as much as possible..... well... i got the .bin file i needed, put it in the /Bios directory, go to start the game, and i get the old "The game could not be started. (80020001)" error.... possibly having a file in the wrong directory, so just to narrow that off totally, i took every file and copy every file to ever single directory...... find out that that apparently isint what i am doing wrong, because it still gives me the same error.... possibly something i am missing? My current set up gives all the files you included in basicly every folder (because thats where i left off) as well as the .bin in the BIOS folder. at this point i am stumped because as i said... new to the scene, hopefing alot of this clears up, as im taking programming classes starting next semester.

Don't try to hide the corrupted icon if you are. The folders HAVE to be named PSPSONE right now, so adding spaces or underscores ( _ ) to try and hide it will give you that error.

I think it's about time to move this into Software.

wrt to PS1 games running in 640x480 and demos running in 320x240. I think you'll find that many games boot into the hi-res mode to show logos and things, then drop back to low-res for the 3d. The PS1 really couldn't manage a high-res textured output. Also, 640x480 is often, if not always, interlaced.

I meant to post that "Progress" message to this thread last night, looks like I missed. Well, anyways, for those who missed it, I managed to get some games (Driver, Dragon Ball Z Final Bout) to work with my emulator. I've got .BIN/CUE support working now. The Driver.Bin file was about 650MB, and the DBZ bin was about 150. My mem stick is only a 256 MB, so I had to test on my psp with DBZ.

Now that I've got .BIN support working nicely, I'm going to add compression through zlib so that the .bin files will be compressed to .gz files. After a few tests, It looks like most Bin's can be compressed by 50-65%. I'm going to work on a resource tool to remove/stub psx movies to help shrink things a bit. But for right now, I'm still working on my recompiler.

so is it safe to assume that this emulator will not be *.iso compliant? whatever's fine for me, i can rip into any extension. and how exactly do you compress into the *.gz extension?

PacManFan · Joined: 25 Jun 2005 Posts: 66

Well,

After replacing just a few file i/o routines with thier zlib equivalant, I now have .bin g'zipped files working. I compressed DBZ Final Bout from 158 MB bin file to a 70MB .gz file, and it actually loads faster! I think this is beacuse the i/o is so slow on the PSP mem stick.

If you want to know more about GZip , Google for it and find youself a nice windows frontend for it. GZip is basically a program like zip based on the ZLib source.

do you have some links that talks about recompiller ?
i'd like to understand how it works ^^
dont know if it writes code to a file then loads it like a elf or what,

PacManFan · Joined: 25 Jun 2005 Posts: 66

Google for "dynamic recompiler" or "Binary address translator" or "dynamic recompilation"

It writes it's code to a block of memory, then it calls that block of memory as though it were a function.

It's a type of self-modifying code.

Take a look at the source for pcsx or ultrahle, they've both got dynamic recompilers and interpreters.

i would suggest the following for controler input.

L1 = L1
R = R1
analog up+L1 = L2 / R1 = R2
analog down+L1 = L1+L2 / R1+R2
analog left/right + select = Menu

saves complicated button combo's for trivial tasks, and besides that people suggesting "select+<key>", doesnt work on a psx emulator because most psx games use the select button

scph1001.bin where do u gt this file from

Google. It is an illegal file so I am not going to give you a link.
