    Actually nullDCe the goal isn't 100% compatibility.Thats the work for the pc version.nullDCe will generally simplify the code by making many assumtions about how the games will use the hardware.Generally this shound't have much effect on games, but it will affect some things (ie, mmu and smc are...

    Pandora's Emulators - What Will Work And What Won't

    That'd make the game so much less fun ;)

    Most of these devices register as normal HID pads, so they should work with linux (well, i have 2 and both of em work as normal HID pads, but i don't use linux).I don't know specifically for pandora.

    Yeah, clocks are 500/55

    Crazy Taxi problems on psp were because psp's gpu just *ingores* triangles that fall outside the clipping region.

    With full kernel access you can work out some tricks most likely .. but i don't really think its worth.MMU translation isn't the only problem .. And most of the wince games have varius performance/quality issues so meh :P

    Yeah, there hasn't.PSP side had even less psp specific work (but i did have to re-work some parts so that it'l work with lower mem requirements).

    Also note that wince (yes, the microsoft OS) based games won't run.That includes Sega Rally 2, Tomb raider, Half Life and a few others.These games require full mmu emulations and we don't plan to add it. fischju2000: The arm code has much more work than the psp one so speeds can't really be...

    Nulldce On The Beagleboard

    Generally i have bad experience from ordering stuff from USA.Customs randomly delays packages and then asks for entrance fee.But since its electronics i'l try to justify it as 'university project related hardware' and hope for the best :P 6x overclock ? 3 ghz ? yay

    Nulldce On The Beagleboard

    Actually no, if it gets anywhere near playable speeds is gonna be thanks to the amount of work to speed it up.As things are now, it needs ~6x speedup to get playable and no amount of over clocking will help that .. @Chip: Shipping from US takes a long, long time .. and most likely will get...

    Nulldce On The Beagleboard

    Actually, according to pvr docs the compressions used are totally different.Dreamcast uses a simple 256 2x2 pixel palette that is very simple to downsample to a normal paletted texture (thats what i do on psp).

    Nulldce On The Beagleboard

    It needs a vcore bump to get to 600 mhz, from 500.I don't think you'l get it at 900 without changning vcore. Oh, and how are your 5 year old pandoras btw? Did you build a time machine and went back 5 years and now you can report they work :blink:.All these figures are based on speculation...

    Nulldce On The Beagleboard

    It's not that unusual for the cache to run on a different clock than the cpu itself (the L2 cache, not L1).I must say i have never used overclocking on a protable device, but on pc the memory clock is indepedant.Other OMAP chips are higher spec'd, but as far as they know they use a different...

    Nulldce On The Beagleboard

    Memory will also get overclocked? I assumed it will stay at the same speed .. but then maby not.Are the caches also timed form the same clock? Still, i don't see someone running the arm @ 900 mhz for large periods of time, on a closed case with no cooling and not causing permanent damage.ARM is...

    Nulldce On The Beagleboard

    Actually, arm isn't that much different from x86 anymore (its getting superscallar, and then out of order .. with big caches).And x86 can get a 30+% overclock without vcorre adjusting.Cortex needs its voltage up to 1.35v for 600 mhz ( from 1.2v needed for 500 mhz).Also the limited cooling of...

    Nulldce On The Beagleboard

    There is a very basic rec, just split blocks and recompiles 6 or so opcodes (add, sub,and, or , xor .. and maby a few more ..).For the rest it fallbacks to the interpreter.Its running underclocked (but less than the psp version -- all fpu ops are assumed to take a single cycle).As with the psp...
