Major Version 5 (Current 5.6)

New Features

• Ability to wipe SMB/LL/LL-EXT records under settings.
• Added tavenwebb2002 to the loader. Huge congratulations on the world record.
• Added real-time counter for each level (Records saved in WRAM).
  • Your time & PB is presented at the end of each level.
  • All PBs for each level and game can be viewed from the loader menu.
• Allows you to start directly on Second Quest in Super Mario Bros (Press B on title).
• Added Slow Motion feature (accessible from pause menu). Kinda conceptual and experimental at this point.
• Added Frame Advance. Set SLOMO in pause menu to ADV. To advance frame, press A on controller two. If you dont have two controllers you will softlock :)

• Fix “Restart Level” that would glitch Lost Levels in some scenarios.
• Fix bug where only parts of the font-set was copied if using a custom one.
• Lots of other smaller things…

Persistence

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.

• Pause completely freezes the game (does not advance frame rules).

• And a lot more…
