ricoh (aopen) firmware flasher

[obs]

does anyone have an older version of the ricoh firmware flasher?

RFLASH.EXE
i'm looking for v4.10 or older (circa 2000)

i have a suspicion that the new aopen 16/10/32 (CRW1632) writer is the same as the 12/10/32 UDMA33 (CRW1232PRO) and i want to try to flash it, but of course the newer rflash programs does some #####.

i want to try the same procedure as with flashing the old 6x -> 8x as per

(the firmware links there don't work, by the way)

thanks.
