|  Re: SD2IEC Fast Irq Loader (possible?)
Finally I could spend time on testing the loader (in fact I've tested it earlier I just had time to record it). The whole test (about 5 mins) is on YouTube. Sorry, the video is uncut so be patient to see some focusing in the beginning.
Results: (loading 48k, 194 blocks.
1551: 1676 frames (~34 sec)
1541 serial: 1810 frames (~36 sec)
1541 parallel: 1671 frames (~34 sec)
SDIEC: 951 frames (~19 sec)
1581: 1134 frames (~23 sec)
As I already stated: the main concept of the loader was compatibility so speed optimizations can come later (if ever).
These speeds are quite slow if we compare to state-of-the art track loaders (for example Krill's loader claims to have 7k/sec loading speed).
