1571 Burst Fastloader
So the Stock Burst loader gets 50% speed of a AR5 64 non burst loader... sure the AR5 has to turn the screen off, but as it is doing a 2 bit transfer vs the 8bit hardware of the Burst seems a bit wrong.
Does anybody know of a faster burst loader routine? PAL, NTSC version would be nice as well, but PAL only is cool.
I would like to be able to load a sector, just get the 254 bytes out of it. For speed I would think it would be best to tell the 1571/81 to load sector to RAM, then later I come back and pick it up. Also I think being able to do the transfer in smaller blocks, say 64bytes, 32 etc depending on how long it takes would be handy, but something I should be able to make work given a code base to modify. |
