This is a custom firmware build for the 1541 Ultimate II by Daniel Kahlin (tlr).

This version of the firmware addresses a few things that needed improvements.

Full History:

• Rebased to the 2.3 release. (svn r88)
• Rebased to the 2.2 release. (svn r71)
• Added GPL 3.0 license as stated by Gideon in the 1541 Ultimate-II (Fixes Bug 110 “License file (GPL) missing in source repository.”)
• Fixed filename length in print out during DMA loading.
• Added “Real Run” for files inside .d64 files which mounts, loads and runs using the BASIC prompt.
• Added “Run Tape” for .tap files which mounts tap and does LOAD/RUN using the BASIC prompt.
• Added “Run Disk” for .d64 and .g64 files which mounts, loads and runs “*” using the BASIC prompt.
• Added detection of cyclic links in .d64 directories and files. (Fixes Bug 94 “Hang when entering diskimage.”)
• Added sanity check of sector links in .d64 directories and files.
• Search until end of directory, even when hitting files with t=0. (Fixes Bug 98 “No dir listing with DEL file linked to T0, S0.”)
• Based on the 2.1 release. (svn r65)
• RUN/LOAD/mount has been reworked to hopefully be more clean. (Fixes Bug 109 “CLR/HOME ctrl code sometimes visible on running file from browser.”)
• Made DMA loading simulate the look of normal loading.
• Corrected mixup of disk id. (Fixes Bug 79 “id1 & id2 mixed in disk_image.cc (Skate or Die disk/sector id bug)”)
• Cherry-picked fix for SDCard rename from trunk. (svn r66) (Fixes Bug 105 “Renaming SDCard via U-Menu corrupts root directory.”)
• Submenues can now be exited using CRSR-left in addition to R/S. (Implements Wish 77 “Exit submenu using CRSR-left in file browser.”)
