content: This was surprisingly and impressively well done. Though emulated to an Amiga 500 with 512k chip ram, 512k fast ram, and 2 floppy drives, it would function identically on a Amiga 1000 from 1986 with the same ram and drive setup.

content: This just shows how far ahead of everyone else the Amiga was when it was introduced.I might even be encouraged to dig out my old Amiga 1000 and try and fire it up again.

It has those RIFA caps at the AC input which should absolutely change before even plugging it in as well as the main electrolytic one tends to leak.Yes, the demo should work as the source disks are available.

content: It's smooth as silk on my A4000. Plus the AGA chipset runs it in 256 color mode, though you could call that cheating.Though I don't have my A3000 anymore, a 25MHz 68030 should still cream a stock Amiga with a 7MHz 68000.Though, I've seen 60Mhz & 100MHz 68060 equipped A1200s running the official ID Quake1 recompiled for the Motorola cpu, but those accelerators didn't come into play until after the death of Commodore.

content: Quote from: BrianHG on February 05, 2023, 05:05:24 amAmazing how talented coders still find new ways to squeeze the last bit of performance from these old machines.Original Doom recompiled for the Atari Falcon (16 MHz 68030) barely did 2 or 3 fps or didn't even start because of lack of RAM.The same rewritten to utilize the Falcon's DSP, some modern rendering techniques and a bit of intelligent optimizations suddenly makes it perfectly playable on an unaccelerated stock machine (16 MHz, 4MB RAM):
