|  Re: Cartridge for Burst mode
I have split this project into two on Github:
Hardware https://github.com/ytmytm/plus4-burstcart - focus is on the VIA version, which is the easiest to make and just works
Software - https://github.com/ytmytm/plus4-parobek - the ROM is in separate repository because it is useful on its own, even without BurstCart. You can download it from the releases section on GitHub and try it out in YaPe.
I called that ROM "Parobek" (Polish for hired farmhand). It includes features that became critical to me after years of using Action Replay on C64 and The Servant on C128.
I will be using it as a C2 cartridge on tcbm2sd as well.
Features:
- works from any location - internal, external C1 or C2
- correctly registers the function key for each case
- startup menu
- DOS wedge with @, $, / commands
- function key launches Directory Browser (with fastloaders)
The correct fastloader is detected at runtime, so the same ROM can support various hardware configurations.
Out of the box:
- 1551 based on Hypaload 4.7, works for devices #8 and #9 (tested in YaPe)
- tcbm2sd fastloader, also for devices #8 and #9
With BurstCart (VIA):
- 1541 with parallel cable, hardware handshake
- even faster mode for 1541 with parallel cable and 1541 RAMBOard with patched ROM (CBM DOS or JiffyDOS or SpeedDOS)
- burst (fast serial) for 1570/71/81 (tested with 1581)
Other interfaces:
- 1541 with parallel cable using 8255 (PIO) or 6529 (PPI) interfaces (tested in YaPe)
Two big omissions are SD2IEC and a plain 1541 on IEC bus.
Since the current setup completely fulfills my own needs, I would welcome any contributions  .
