1541 Ultimate I / II: New firmware v2.0RCA
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…)
Some major fix:
- Freezer bug fixed.
- Cartridge Freezer reactivated after DMA load.
- MK1 support completed.
- Tiny fix added for USB (connecting a powered hub caused the C64 to be powered by the hub!!)
- Updater fixed for older FPGAs that don’t support the capability register.
- Memory controller for MK1: removed DACK for write cycles.
- Added dummy I/O clients, for missing modules in MK1 FPGA.
- Rewritten first bootloader (…)
- Added second drive support in software.
- Added audio switch. If second drive is available, it will be available on the right channel.
- ‘Chars’ linked instead of loaded from Flash. MK1 doesn’t have charset in flash…
