SD2Snes Firmware v0.1.7 (Beta/Preview 3) released

October 19th, 2014 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Full Changelog:

A minor update, mainly in the name of stability. This hopefully eliminates glitches unrelated to the in-game buttons on some consoles, e.g. Seiken Densetsu 3 rebooting intermittently or graphical glitches in DKC 2+3, that had been introduced with v0.1.7 preview 1.

  • Reintroduce more aggressive filtering for control and address lines from the SNES, previously removed after v0.1.6
  • Unify and centralize signal edge detection for all sub-units (e.g. S-RTC, MSU1, BSX, DSP etc.) instead of each unit having its own (slightly different) edge detection.
  • In-game controller scan has become slightly more time effective under certain circumstances (Auto Joypad Read enabled but no NMIs).
  • In-game hooks are now disabled for 10 seconds after loading or resetting a game to help certain games get past their boot screens. This will be configurable in the final.
  • Reconfigure the FPGA only when necessary on warm reset, speeding up “reset to sd2snes menu” by a couple hundred milliseconds.
  • Fix an MMIO access priority bug for DSPx.
  • Fix BS-X ROM detection for games with 2 startups left.
  • Fix directory browsing being broken after setting the clock.

Commodore CBM 4040 Dual Drive Floppy Disk

Commodore CBM 4040 Dual Drive Floppy Disk

I must thank Davide M. for the donation.

The Commodore 4040 is the replacement for the previous models 2040 (USA) and 3040 (Europe). It’s a dual drive 5¼” floppy disk subsystem for Commodore International computers. It uses a wide case form, and uses the IEEE-488 interface common to Commodore PET/CBM computers.

These drive models use a similar single density, single side floppy data storage format to that used by the Commodore 1541 drive, but with a slightly different data marker indicating which model originally formatted the disk. The low-level disk format was similar enough to allow reading between models, but different enough that one series of drive models could not reliably write to disks formatted with one of the other model series.
