Here is an example of a XOR texture, created by g0blinish ![]() The GBASCALC($F847) procedure is used to calculate the address of the horizontal line : IN:reg.A=Y, out : GBASL/GBASH($26/$27)=address. The screen structure is called memory holes( ). Lores and Hires can be mixed modes and full-graphics Applewin Version 1.30.5 includes a host of new features and bug fixes including: Change 972 Add SNES MAX card (in slots 3, 4 or 5) to support up to 2 SNES (or 12-button) controllers. Deater did manage a color-bar style effect in double-hires in 128B but that was doing some crazy tricks with the firmware BASIC routines, definitely not direct-access. Tom Charlesworth has released a new version of the Applewin Apple II Emulator for Windows. Double-hires is even crazier on top of that. To do hires you need to divide by 7 which as you can imagine is a bit difficult to do compactly on 6502. The only fast way to do things is with large lookup tables. ![]() woz support in recently - which allows for perfect nibble disk images to run even with the original copy protection intact Our last big update was better NTSC emulation. However for sizecoding, you almost never want to do direct-access to graphics for Apple II in size-coding because the Apple II graphics modes are horrible. Even though the emulator has been stable for years we continue to refine it adding features, add QoL improvements, and fix bugs as those are never ending. If/when we switch to building as a 64-bit app, then this is worth testing.512-767 $200-$2FF KEYBOARD CHARACTER BUFFERħ68-975 $300-$3CF OFTEN AVAILABLE AS FREE SPACE FOR USER PROGRAMSġ024-2047 $400-$7FF TEXT AND LO-RES GRAPHICS PAGE 1 <- !!!Ģ048-3071 $800-$BFF TEXT AND LO-RES GRAPHICS PAGE 2 OR FREE SPACEģ072-8191 $C00-$1FFF FREE SPACE UNLESS RAM APPLESOFT IS IN USEĨ192-16383 $2000-$3FFF HI-RES PAGE 1 OR FREE SPACE <- !!!ġ6384-24575 $4000-$5FFF HI-RES PAGE 2 OR FREE SPACEĢ4576-38999 $6000-$95FF FREE SPACE AND STRING STORAGEĤ9152-53247 $C000-$CFFF I/O HARDWARE (RESERVED)ĥ3248-57343 $D000-$DFFF APPLESOFT IN LANGUAGE CARD OR ROMĥ7344-63487 $E000-$F7FF APPLESOFT OR INTEGER BASIC IN LANGUAGE CARD OR ROMĦ3488-65535 $F800-$FFFF SYSTEM MONITOR Display Graphics Modes Text Mode 40x24, for Apple IIe available 80x25 - use PR#3 for switch mode, or hardware switch LowRes 40x48, 16 colors: Hires mode 280x192,6 colors: AppleWin.exe is a 32-bit app, so replacing this 32-bit add with a 64-bit add will affect performance. ULONG is a 32-bit unsigned int, so it's 32-bit maths. Well after every opcode there's a CYC() where ULONG uExecutedCycles gets a few cycles added to each it opcode. Would it not be easier to update it directly in Cpu65C02() rather than updating the local uExecutedCycles? and then g_nCumulativeCycles is always accurate. Calling CpuCalcCycles() twice is fine, as for the 2nd call the cycle delta is zero. no video update), eg: - Benchmarks - Pure Video FPS: 2860 hires, 2868 text Pure CPU MHz: 10.3 (video update) Pure CPU MHz: 241. ![]() AppleWin is the best Apple IIe emulator we have encountered so far to play. So added a 2nd 'Pure CPU MHz' for full-speed (ie. So when you need cycle-accuracy then you call CpuCalcCycles(). that was the idea behind the software-solution for the speed. It's a "just in time" calculation of g_nCumulativeCycles, so that it's only calculated when it's actually needed. Why this double layer to update g_nCumulativeCycles? This needs refactoring so that it's nCyclesExecuted for all cases. This is a hang over from a previous, much older version of AppleWin. Why is the variable always called nCyclesLeft? It feels more like a nCyclesExecuted. Features sound emulation through either the PC speaker or a sound card, and the Super Serial Card is emulated through PC COM ports.
