      i think part of the confusion is that mame-libretro is a rom folder installed in ~/RetroPie/ where you put your roms in for any of the libretro MAME cores. eg, this folder is used for the default lr-mame2003 core that uses the 0.78 MAME romset. however, there is also a 'lr-mame' ("libretro-mame") emulator that is an experimental (not installed by default), that uses the current (or close to) MAME romset.

      in any case, put your 0.78 roms in /mame-libretro/, use lr-mame2003, and if you get any issues please post the verbose log as instructed.

      @grant2258 Hi Grant - yes I think I've realised that this is the problem. The default RetroArch setup creates a virtual gamepad and binds both virtual gamepad and keyboard. I think the problem with Defender is that these mappings overlap - so the virtual gamepad is triggering as well as producing a keypress, and these are both bound to different things (eg thrust AND fire).

      Thanks for your help!

      How to get 8-Way / 4-Way joystick controls in Defender and Stargate

      @jdoc said in How to get 8-Way / 4-Way joystick controls in Defender and Stargate:

      Just had to nuke and pave my system, but discovered that mame2003 changed a bit. This cheat still works, but “mame2003-cheats” has changed to “mame2003-cheat_input_ports”.

      So changing mame2003-cheat_input_ports = “disabled” to mame2003-cheat_input_ports = “enabled” will make this work again.

      Thanks for this. This may be the reason that the MS Pacman speed button stopped working a few years ago, too. I'm gonna give this a try and see if it helps there.

      EDIT: Confirmed. This fixed the issue. I posted on this forum about it ages ago and nobody had any idea what was wrong. Thanks!

      Yes, the method to make two-handed "tank" controls work on a single 8-way joystick does not require any cheats, just a clever set of controls mapped to what is sometimes called a "tankstick". The mapping makes use of <CODE_NOT> logic where you are actually excluding certain input combinations. MAME lets you setup mappings like this by using a double-tap of an input while in the GUI menu which changes it to a <NOT>, so if you do several inputs in rapid succession, before MAME accepts an entry, you can make some combinations that work in interesting ways.

      Here's a mapping for a single 8-way joystick to control two tank sticks like Battlezone:

      Game Control Mapped to Right/Up Up <not> Right or Left <not> Down Right/Down Down <not> Right or Right <not> Up <not> Down Left/Up Up <not> Left or Right <not> Down Left/Down Down <not> Left or Left <not> Up <not> Down

      There is an odd situation for Keyboard controller users in lr-mame2003 that requires you to first set all retroarch inputs to NUL using a per-rom config file if you want to do this. You can read about it here.
