This port requires a C64/C128 with a SuperCPU v2 and 16MB RAM. PAL, NTSC (old and new) as well as DREAN should be supported but it has only been tested on real PAL hardware. text/html 2014-11-03T16:07:56+02:00 https://scpu.amidog.se/doku.php?id=scpu:mipsrecompiler&rev=1415027276&do=diff This is a static MIPS-I recompiler for a SuperCPU equiped C64. That is, it will take a MIPS-I executable and translate the MIPS opcodes into 65816 ones. The recompiler is written in ANSI-C, compiled using GCC and recompiled into 65816 code using itself. Or in other words, a x86 compile of the recompiler is used to recompile a MIPS-I compile of the recompiler :-) There is also a Win32 build included, which likely is more usefull than the SuperCPU native one. text/html 2014-09-05T18:20:24+02:00 https://scpu.amidog.se/doku.php?id=scpu:synthmark64&rev=1409934024&do=diff This is an updated version of the benchmark program found here. List of changes below. * Added machine information at the bottom of the menu screen. CPU (6502/65C02/65816), RAM and video system (PAL/NTSC) * Added SuperCPU optimization options: Optimization SuperCPU v1 SuperCPU v2 DefaultMirror $0000-$ffffMirror $0200-$ffffNoneMirror $0000-$ffffMirror $0000-$ffffFullMirror $0400-$07ffMirror no memory * Changed write tests from page $ff to $fe since $ff00 is an REU address used to trigger p… text/html 2014-09-29T10:28:54+02:00 https://scpu.amidog.se/doku.php?id=scpu:synthmark816&rev=1411979334&do=diff This test is based on Synthmark64 but focus more on real-life operations and less on raw memory performance. It also makes use of the 16-bit mode of the 65816 in order to highlight both pros and cons of using the larger accumulator and index registers. When run on 65816 it will show two columns, one where the CPU is in 8-bit mode and one where it is in 16-bit mode. Since switching between 8-bit and 16-bit mode takes time, the 8-bit operations will be quite a bit slower when the CPU is in 16-bit … text/html 2017-05-24T16:30:08+02:00 https://scpu.amidog.se/doku.php?id=scpu:wolf3d&rev=1495636208&do=diff This is a port of Wolfenstein 3D based on the original ID software source code release. This port requires a C64/C128 with a SuperCPU v2 and 16MB RAM. PAL, NTSC (old and new) as well as DREAN should be supported but it has only been tested on real PAL hardware.
