A new version of the firmware for the interface 1541 Ultimate I / II is released.

This version also runs on the Ultimate-I! (Of course, only the features that MK1-hardware supports will show.. no RTC, no USB, no C2N (tape), etc…)

This is a MAJOR update from RCA! Please note that former versions had issues with writing back data to .D64 images.

Your copies that you made with former 2.0RCx versions might be corrupt!!

Major improvement in latest release:

• Added: Small step made to supporting block sizes other than 512 bytes (for CDROM, which I want to support soon!)
• Added: Update changed to flash all roms too…
• Added: Boot FPGA definitions added for booting with Winbond Flash.
• Added: USB hub support (high speed devices only!)
• Added: C64 reset included in 1541 reset (optional)
