ActionMax for Pi

---

Following the release of Debian Bookworm, this emulator is now obsolete and will be archived.

---

Original Context follows:

This is a companion emulator for hypseus-singe. It allows certain generations of SBC's (inc. Raspberry Pi) to overcome display driver issues with SDL2 reading pixel data from the display. It is designed to run in a libretro style environment as dictated by the -retropath argument in Hypseus Singe.

ActionMax was a VHS based lightgun game: Wikipedia

Hypseus can run ActionMax games on most platforms, use Hypseus when possible.

If "Targets Disabled" is displayed in Hypseus Singe, then try this emulator.

This emulator uses SDL1.2 libraries and is based around the original Singe by Scott Duensing.

It should be used as a ROM specific emulator for ActionMax games:

38ambushalley bluethunder hydrosub2021 popsghostly sonicfury

It can be operated by joystick, mouse or lightgun as originally intended.

See further information in discussions.

RetroPie install

Use actionmax.sh for RetroPie-Setup

wget https://raw.githubusercontent.com/DirtBagXon/actionmax-pi/main/actionmax.sh -O $HOME/RetroPie-Setup/scriptmodules/emulators/actionmax.sh

sudo $HOME/RetroPie-Setup/retropie_setup.sh

The package will appear in (exp)

Use .commands file for optional argument as per Hypseus/Daphne.

Configuration

See README on ActionMax ROM setup in libretro style environments here

Configuration should be made within singeinput.ini as per Daphne SDL1 keycodes.

Run

Use standard Daphne and Singe arguments with this emulator.

Note: -script is not used in this implementation. The .singe file should be the first argument.

actionmax.bin 38ambushalley.singe -framefile 38ambushalley.txt -homedir "/opt/retropie/emulators/actionmax" -fullscreen_window
