The Atari Jaguar console emulator has been updated - BigPEmu.

- Added a script for Raiden touch control. Ship automatically travels to the touch point and auto-fires when held, with a 2-finger tap to trigger bombs
- Added a script for Vid Grid touch control. Drag and drop
- Added a script for Towers II touch control. (with an option to uncap the framerate) In-game menu cursor is touch-driven, 2-finger tap exits the menu
- Added a script for Myst touch control. Hold to drag the cursor, tap to activate
- Added some scripting functionality to allow setting custom read/write handlers for non-RAM/ROM memory regions
- The iOS port now prompts the user to determine their battery/heat versus performance preference on first run. (since we can't just be energy-efficient without the iOS scheduler punishing us, and I'm not having any luck getting anyone to read the FAQ/user manual)
- The iOS port now has a separate "Connected Idle Time" setting, which defaults to 3.0 and is used instead of "Overlay Idle Time" when at least one external device is connected. (workaround for the same FAQ/user manual problem above)
- Added lots of random new scripting functionality
- Fixed game thumbnails rendering at the incorrect scale in portrait mode
