Samurai Warrior was never released on cartridge, so I built one from C64iStanbul’s three-chip board, a burned 27C512 and Marko Šolajić’s Magic Desk project.
A modern recreation of the Mikro-Plus interface that sank Mikro-Gen: built from a PCBWay board, foiled by tall sockets, then fixed and tested on a 48K Spectrum.
A step by step build of Stephen Smith’s Romantic Robot Multiface 128 recreation for the ZX Spectrum, from bare PCB and EPROM programming to the NMI menu.
Building a TL866 MiniPro adapter for 27C400 to 27C322 EPROMs, then rescuing a legless Amiga A600 Kickstart ROM by burning it to a new chip.
Building an Epyx FastLoad cartridge for the Commodore 64, working around remarked AliExpress EPROMs, and timing SD2IEC loads with and without it.
