Docs / Launching PRG files
Mechanism
| Mechanism | Behaviour |
|---|---|
| Inject | REST run_prg streams the file directly into RAM. Fastest path. No drive state changes. |
| Mount A | Mounts the parent disk image on virtual drive 8. LOAD"$",8 lists, LOAD"PRG",8 loads. |
| Mount B | Same, on drive 9. Useful when you want drive 8 free for another disk. |
Pre-reset
- None - launch into the current C64 state. Safest default.
- Hard reset - chip reset; RAM cleared, clean BASIC prompt.
- Reboot Ultimate - full firmware reboot. Disconnects active sessions. Always confirms before running. Gated behind the Allow Reboot setting in Settings ▸ Launching.
Post-action
- Run - executes RUN after load. Default for most users.
- Load only - leaves the C64 at the BASIC ready prompt for inspection.
F1 modifier matrix
F1 alone runs the configured default. Hold modifiers to override:
| Keys | Action |
|---|---|
| F1 | Default mechanism + run |
| Shift+F1 | Force Mount A |
| Ctrl+F1 | Force Mount B |
| Alt+F1 | Load only (no run) |
| Ctrl+Alt+F1 | Hard reset, then default launch |
| Ctrl+Alt+Shift+F1 | Reboot Ultimate, then default launch (must be enabled) |
