Uae4arm (arm jit)
TomB released first alpha version UAE with ARM JIT engine
more info http://boards.openpandora.org/topic/...alpha-uae4arm/ sources included |
This is fantastic.. trying it now! I prefer the gui already ;)

comparison for jit and non-jit mode with android port of uae4arm (device thl w200, 4x cortex a7 1.5ghz)

wow
|
that is impressive :)

"We lost some performance, because the newcpu core is a bit slower than FAME/C" Did you make some benchmark between UAE4ALL with Fame and this version with JIT ? The TomB sentence is unclear... I could look at what would be the gain on Raspberry Pi 2 anyway... |
Sysinfo (Dhystones)
nojit - 12104 jit - 90153 famec(115mhz) - 26997 AIBB (CPU) nojit - 12.51 jit - 44.02 famec(115mhz) - 14.75 AIBB (WritePixel) nojit - 7.75 jit - 47.27 famec(115Mhz) - 25.08 But all this results are very relative famec in current state not support calculating real speed (for example results in benchmark will be same for slow and fast devices) In real games&demos, for example i tested with game Breathless AGA performance newcpu jit and famec (56Mhz) are very similar for my device |
Does the new (slower) core improve things like Cinemaware Wings (wildly fast or slow, depending on the mission type) or the ending credits of the Alcatraz Odyssey demo (repeated characters)?

Odyssey demo - looped at one scene without any continue. I saw same problem on E-UAE with it.

Multiplatform source (added sdl based sound.cpp)
https://dl.dropboxusercontent.com/u/...5052015.tar.gz Android test (alpha) version https://dl.dropboxusercontent.com/u/...t-05052015.apk known android-related problems: - gui element is too small, it can be problem for smartphones (will be fixed soon) - onscreen control UI - not present (will be added soon). - (update) HDF adding - works (but not stable, adding can works after few attempts) (will be fixed soon) |
Nice work. I hope to try this on my OUYA like UAE4ALL2
|
I can't get this to make on my rpi2. Any tips?

You can try my work-in-progress version: http://fdarcel.free.fr/uae4arm-rpi-beta.bz2 Sound and double buffering using dispmanX are working. launch it from Xwin, use ctrl to go back to menu. it's not fullscreen since I don't close dispmanX when going back to menu... But you'll see that speedwise there is not so much improvement... |
Is there a detailed guide on how to get this on a rpie2? I'm a Linux noob. And a recent purchaser of a raspberry pie 2 and would love to get a decent amiga emulator on it?

In my opinion this is a great improvement. Games like Alien Breed 3D II run much smoother under this implementation - 040 at the faster emulatable speed on an overclocked rpi2. Now, when you can enable full screen it'll be fabulous. There's a snag with the controls at the moment though - it's not registering button presses on either my ds4 pad, USB competition pro joystick or 9-pin original competition pro joystick. Thank you for taking the time to upload this, it's appreciated. |
UAE4ARM - HDF file selection works on my JXD S7800B. It does not work on my Samsung Galaxy Ace 4. I was able to transfer the saved config file from the S7800 to the Ace 4 and edit it to reflect the phone's SD card structure. I can use the HDF file this way.

Very interesting to see on benchmark speed for different arm devices (as Pandora, PI2, or android devices) for comparison. Maybe someone can test with modern cores as Cortex A15/A17 or with faster cpu ?
|
What graphics drivers are you using for the RasPi2? I've run into a few programs that try to access the graphics core under Raspbian that require OpenGL/Mesa or use the X-Server only to be greeted by unaccelerated framebuffer support. Is there an OpenGL-ES or -ES2 backend for the emulator?
