Disk2easyflash 99%

If you’ve been living under a PET, EasyFlash is a cartridge for the C64 that acts like a Swiss Army knife for ROMs. Usually, you load .CRT files onto an SD card and play. But what about all those disk-based games that never got a cartridge release? You know, the ones that load custom fast-loaders, have 20-level passwords, or weird save systems?

You can’t just drop a .D64 file onto an EasyFlash and press play. Or can you?

Even experienced users hit snags. Here is your cheat sheet for common issues.

Error: "No single-file program found"

Error: "Unsupported loader type"

Error: Game loads, but freezes on title screen

I’m using an EasyFlash 3 cartridge. Here is how I converted The Last V8 from a grindy disk experience to an instant-start cartridge. disk2easyflash

The moment of truth: I dragged the resulting .CRT file onto my EasyFlash 3’s SD card, popped it into the C64, and reset.

Instant. No "SEARCHING FOR $." No 20-second pause. The title screen was there before the monitor finished warming up.

Open your terminal/command prompt. Navigate to your folder containing the .d64 and disk2easyflash.py. If you’ve been living under a PET, EasyFlash

The basic syntax is:

python disk2easyflash.py game.d64 game.crt

However, for best results, you need flags. Many games require basic disk swaps. If your game has multiple files (e.g., "PROGRAM", "LEVELS", "DATA"), use the -c flag:

python disk2easyflash.py -c "PROGRAM,LEVELS,DATA" game.d64 game.crt

If the game has a custom loader (like Ocean Loader 4 or Rob Hubbard music routines), use the -f (force) flag: Error: "Unsupported loader type"

python disk2easyflash.py -f -s 5 game.d64 game.crt

(The -s 5 adjusts the loading speed sensitivity for stubborn titles.)

The EasyFlash has a 1MB flash chip. Disk2easyflash organizes the game into banks. Each bank can be 8KB or 16KB. The tool creates a "boot bank" and then "data banks" for the rest of the program. Finally, it outputs a single .crt file ready for your programmer.
