The original 1541 (and 1541-II) floppy disk drive were pretty slow. The serial port, which connected to teh FDDs is doing about 400Bytes/sec (C64-Wiki: Serial Port). To speed up the disk operations, faster loaders are used.
Some fast loaders work with an unmodified 1541, some require a corresponding ROM inside the 1541, some are an alternative kernal (ROM) for the C64, some work from a cartridge and some are just part of the software. Some require a parallel connection between the 1541 and the user port (or a cartridge) of the C64.
Since I was working on a SpeedDOS adapter for the 1541 and 1541-II and the C64, I got interested in comparing the load speeds of different fast loaders to compare it with SpeedDOS.
I used one floppy disk that contains Bubble Bobble as a bench mark. There are different versions of this programs available, for a good comparison, it is required to use exactly my copy: 177 Blocks, cracked by Hotline, 26.09.1987.
First, I have loaded Bubble Bobble with the original Commodore ROMs on both, the 1541 and the C64. This is my benchmark.
