To keep settings, frame rules and stuff persistent; configure your game system (emulator, PowerPAK, EverDrive etc.) to allow the SMB Practice ROM battery-backed WRAM. Essentially, figure out how to make it so that you can save in Zelda (without savestates), power off the system, and load (without using save states). Then do the same for the SMB Practice ROM.
- Practice both SMB and SMB Lost Levels
- Start the game from any frame rule
- Start on any level.
- Keeps track of prefered start rule for each level.
- Battery backed WRAM for persistent memory.
- Level rules.
- One save state.
- Personal bests.
- Settings.
- Restart the level from the frame-rule you entered.
- Monitor two user-defined RAM addresses.
- Built-in save-states.
- Customizable hotkeys.
- In-game menu with lots of stuff.
- Pause completely freezes the game (does not advance frame rules).
- Practice specific scenarios
- Advanced settings menu in the loader.
- Real-time counter for each level, and persistent records.
- Start directly on the Second Quest in SMB1.
- Practice with Slow Motion.
- Practice with Frame Advance (A on second controller to advance. Start on second to exit.).
- And a lot more...
