Spot

[sam fisher]

I hope so!

Edit: More Alpha??? MORE MORE!!!

Why's it called spot?

reminded me of a old java JIT technique which maybe resembles a similiar technique used here

 

[___]

so basically... you are saying... it's running so fast that it blurs on the lcd screen of the gp2x? holy crap...

 

[Tobriand]

Sounds fantastic. Although I imagine the reason it might be blurring is because the BLU firmware underclocked a lot, iirc, didn't it?

 

[Squidge]

I would imagine so, if anyone knows how fast the blu firmware runs, I'm all ears

There's no Dyanrec or JIT techniques used here. Just another MMU hack, Data abort exception handler, and running the Gp32 code completely native (which is currently interrupted 7,200 times a second to process i/o requests, LCD screen registers, LCD redrawing, etc...)

 

[Vimacs]

didnt the fw run at 40 or 66mhz?

 

[Squidge]

Dunno

Maybe the best thing would be to find that pllsetting program for the mmsp2? Then I could calculate what it should be running at in the emu.

Great stuff, squidge

There are values in GP32 Binaries like the FW Menu you can find with a hex Editor to see its frequency. You can edit them to speedup a app (or just to find out its speed). This is what Horscht and me did as a service for GP32 Users a while ago.

Good Luck

See Spot run?

I do recall it ran at 66mhz. For a short time when I was a GP32 newb I actually thought the GP32 HAD a 66mhz processor because that's what it "natively" ran at in the firmware.

Luckily, I haven't been a newb in a long time.

 

[Vimacs]

well, the official developers thought so as well, thats why most of the official games run at the speed the fw sets

 

[sam fisher]

Good old gamepark and their daft lack of information. Where would be have been without them?

 

[yoyoyoyoyoyoyo]

does this run any games yet?

EDIT: caps lock

 

[ste_167]

If it did, do you think there'd 'only' be 8 pages of posts?

See Spot run?

Unlikely, it's currently running on a different system (but arm based) simply because it was easier and no linux or other OS to get in the way (so it just runs on the hardware directly). It could be ported to the GP2X via HH or a Linux Kernel module, but I've just no motivation (or time, currently) to do that.

Maybe I'll port a later version later on in the year? Perhaps towards the end of summer?

 

[Blah]

I don't think any of us would mind if it was a kernel module .

 

[Tobriand]

Nah, Kernel Module of Spot would be great. Include it in Open2x eventually, if that's the way it goes

 

[___]

yeah, that's a great idea. kernel module with open2x and there you go: gp2x with built in backwards compability!!!
