Based on the very cool PCUAE-project I decided to optimize the amiga-emulation on the c64.
Doublebuffering is still a problem ... working on.

Nice job! Yeah we could all play these games on a Pi but there's something extra satisfying about getting the C64 mini or maxi running other platforms, especially emulating it's big brother the Amiga.

How do you get this to work, I having a problem getting PUAE into CD32 mode, it keeps coming up with the A1200 bios screen with the disk on the screen...?

I have tried `puae_model = CD32` no that don't work, tried `model = CD32` no that dose not work too... very odd, its like it dose not know the model switch, I did try running the CD CUE file from the Retroarch menu but it runs out of memory but you can see it tries to run it and uses the cd command to try and mount the CD CUE file but I knew it would do that, it would probably work if I new the switch and how to get PUAE into CD32 mode, cause THEC64 has enough ram to run one emulator or game without the RA menu, the menu uses to much ram so it kills Retroarch cause when it closes it to run a game, the menu is still running in the background so it can show it again if you press Select+Start, RA only hides it so its still using ram. Any help right now wound be great... My plan is, if I can get this working is so you can run it on THEC64 as a Mode in PCUAE and then you be able to load a CD32 game by changing the CD32 game in its UAE file, you can now do that on THEA500 Mini but thats cause it uses Amiberry, Amiberry can not be used on THEC64: 1. Amiberry uses SDL2 that can not be used in THEC64 cause it uses SDL1, I have tried using the SDL2 version of Retroarch and it dose not work on it. 2. THEC64 would not have enough ram to run it and Amiberry would be very slow so not run at full speed, when running the PUAE Amiga Emulator on THEC64 Models it has to run it at frame skip 3 so skipping 3 frames a second for it to run properly, you should see it skipping if you load a game that scrolls across the screen like a shooting game, you see it shudder a bit but runs at the right speed and the games are playable, THEC64 Models SOC(System On a Chip, a bit like a FPGA Chip, CPUs are Alwinner A20 - THEC64 Mini, Alwinner H3 - THEC64/THEVIC20, they are run at the same speed and uses only 2 cores in the CPU, like THEC64 Mini, the H3 is a quad core but only uses 2 cores like the A20 cause the A20 is a duel core CPU so THEC64/THEVIC20 uses the same cpu settings or governors as THEC64 Mini so it runs with 2 cores only and the 3rd core is disabled in the H3) only have 256 MB Ram where THEA500 Mini has a faster SOC(Alwinner H6, it has twice the power than the Alwinner A20/H3 and its 64bit not 32bit even though you can run 32bit code in the H6, most Linux binaries are 32bit code, Amiberry is 64bit thats why THE500 Mini uses a 64bit CPU) and twice the ram, 512MB ram so not 256MB so is a better Linux system and faster system, it is more like the NES/SNES/MD Mini's, the H6 is a A53 Cortex SOC so in par with RPI3(Quad Core 1.2GHz Broadcom BCM2837 64bit CPU from the RPI3 is a A53 Cortex SOC CPU made by Broadcom for RPI Foundation, the RPI has a custom chipset so like the Amiga, most computers from the 80s/90s did, until computer manufactures started copying PC specs in 1995 so started making PC clones). A in A53 stands for ARM, ARM design SOCs so manufactures like Alwinner or Broadcom can make them, ARM was the Acorn Archimedes computer that was made in 1987, it was the British version of the Amiga, it had a ARM CPU in it - Acorn Risc Machine CPU. In 1990 Apple put money into developing the ARM CPU and now its `Advanced Risc Machine`, Apple never like the name `Acorn` cause they were there competitor at the time. ARM CPU was used on the first Apple IPhone in 2007 and the IPad, and then was used in other Mobile Phones and Tablet that used Android, ARM is used in almost every Smartphone now and the rest is history... We would not have the ARM CPU if it was not for the Amiga... The Amiga changed everything. ARM is still a British company and is still Acorn but just with a different name, ARM is what happed to Acorn after Archimedes... Acorn found out they could make more money designing CPUs then making computers.
