Man, this emulator is very slow. Is there any other version that runs better without slowdowns? Thanks

Which game doesn't run at 100% for you?

^ never tried it tbh since I got an ez-flash IV, I do know that on the XBOX gba emulation is not always 100% and that's why I asked what's the deal on the GC

port gpSP and write a PPC dynarec. probably your best bet for easy full speed GBA emulation on GameCube.

yep. piece of cake. :roll:
I had forgotten how cool that emulator is.

Maybe when that HDMI thing becomes real, people will start caring about the GC again and you guys won't have to code every single thing yourselves...

megalomaniac, can you port the optimizations(TILED_RENDERING, https://github.com/libretro/vba-next/co ... 42a5003ca0) from VBA Next by libretro team, Vba-m team to Gamecube?
It is said that with TILED_RENDERING, most game runs at full speed on Wii. The optimizations have been ported to XBoyAdvance v24b03, and it speeds games a lot.
RetroArch has a vba-next core for Gamecube, but due to RAM size problem, it doesn't work at all(crashes after ROM is loaded).
With TILED_RENDERING ported to your unofficial VBA GX, I think many games could be more playable on Gamecube.

Isn't the retroarch people working on a gPSP port?

If that thing runs at 100% speed on the PS2, I guess it should work fine on the GC too...

That's more than double the amount of RAM in a gamecube though.

It's slow because the backing store (SDGecko) holding the loaded ROM file needs to block the CPU to get data out and into a memory cache for the rest of the emulator to read.

If we had a spare 32MB to fully load the ROM files into I'm sure it'd be a lot faster. (If it's not already using ARAM + SDGecko + Virtual Memory)

If that is what you say then maybe loading from WKF or IDE-EXI would make it faster.
Also can the Flipper be used to load data from the SD Gecko ?

But IDE-EXI would be as slow as every other EXI device, because of missing DMA support, right?

It is just a firmware update though so you only need to flash yours.

I never had one, because I never wanted one, because I thought, it would be as slow as every other EXI device :D

Oh lol. Emukidid said it was going to be better than a wkf in the future (and maybe support audio streaming).
