Earthworm Jim 2 pauses when pressing 2 simultaneous opposite directions #204

Closed orobas0 closed 2 years ago

orobas0 commented 3 years ago

Versions: Retroarch (1.9.5) beetle-saturn-libretro (latest nightly buildbot ver.) Earthworm Jim 2 (only tested the USA release) Windows 10 x64

Issue: While playing Earthworm Jim 2 using Retroarch with the beetle-saturn-libretro core and the keyboard as my controller, whenever I press opposite directions simultaneously (left+right or up+down), the game pauses as if I'd pressed the pause button. I need to keep unpausing the game to play because ending up pressing opposite keys when fast actions are needed is pretty common while using keyboard controls.

I can't reproduce the issue using the mednafen emulator itself (1.27.1) or Retroarch + other Sega Saturn cores, so I suspect this is a beetle-saturn-libretro core issue.

Steps to reproduce the issue: Load Earthworm Jim 2 in Retroarch using the beetle-saturn-libretro core, start a new game, press left+right in any moment.

Thank you in advance.

The exact same thing happens in PowerSlave, it is super annoying when you're playing on a keyboard 😓

I've submitted a fix few days ago, if you're curious to test: mednafen_saturn_libretro.zip

It simply adds a core option to enable/disable Up+Down and Left+Right (disabled by default).

Thank you for taking the time to code a workaround yourself. The fix is working properly here!
