How Does The EPYX Fast Load Enhance Loading Speed On A Commodore 64?


In their latest video, Commodore History performs a thorough technical examination to elucidate the functions of the Epyx Fast Load cartridge on a Commodore 64, aimed at accelerating loading operations from a Commodore 1541 disk drive.

Employing a logic analyzer to track signals on the bus, Commodore History meticulously elucidates each step of the process, drawing comparisons between the wire protocols of the Epyx Fast Load and the standard Commodore serial bus. To comprehend the inner workings of the Epyx Fast Load, a comprehensive disassembly of the Fast Load kernel load routine is undertaken (excluding the entire cartridge ROM), encompassing the analysis of the code transferred to the 1541 disk drive by Fast Load.
