Restored from previous forum.

Here's a new v2 image for RPi4 setup for RaspberryJAMMA to use as a dedicated Fix It Felix Jr. It's basically a tweaked Twister OS lite, it's using Box86 and Wine to run the promo cab version of FIFJ.

The v2 release also uses the (I)Fix(ed)itFelixJr game launcher by Howard_Casto on The NEW Build Your Own Arcade Controls forum with permission, see: http://dragonking.arcadecontrols.com/st ... AboutIFIFJ. Many thanks and all credit to Howard_Casto for the improved launcher.

You need to add the game exe and Data folder to the fixitfelix folder on boot partition of the SD card, everything else should be automatic.

Default setup is for low res, 240p.

Fix It Felix Jr dedicated RPi image v2.

this is essentially a modified version of TwisterOS_lite setup purely for Fix It Felix Jr and intended for use with the RaspberryJAMMA JAMMA adaptor (AKA ArPiCade). It uses Linux, Wine and Box86 to run the game which was originally only for Windows. To make 240p full screen possible the (I)Fix(ed)itFelixJr game launcher by Howard_Casto on The NEW Build Your Own Arcade Controls forum is used with permission, see: http://dragonking.arcadecontrols.com/st ... AboutIFIFJ. (I)Fix(ed)itFelixJr also enables some extra settings like freeplay, high score saving and a cocktail mode (currently untested on this image). High score saving is unlikely to work unless the image is safely shut down from the OS prior to cab power off.

Default behaviour is to boot straight to FixItFelixJr. If required the game can be exited with the keyboard shortcut alt+F4. After exiting the game the (I)Fix(ed)itFelixJr settings menu will load automatically. The TwisterOS menubar will also load after exiting the game allowing access to the TwisterOS menus etc. in case they're required. If you want to reboot or properly shut down alt+F4 will open the power menu giving you options for rebooting, power off etc. once all programs have been exited (also using alt+F4 for each program).

As I cannot (legally) include the FixItFelixJr original gamefiles you will need to install them before use. The (I)Fix(ed)itFelixJr launcher files are already installed and do not need to be added.

If your monitor is rotated the wrong way change the rotation using the settings menu. After pressing the save settings option the program will close, alt+F4 and select reboot to make sure the changes are written to the SD card properly.

FIRST BOOT GAME INSTALLATION:
Fix It Felix Jr gamefiles go into /boot/fixitfelix/ - they will be installed automatically at first boot (first boot may take longer than usual). Required files include FixitFelix.exe and the data folder and it's contents. The installation process is only needed to be done once, files will be auto cleaned up as part of the install process.

SETUP:
The default settings are for 240p low res (vertical monitor). Edit /boot/config.txt for high res mode, only use the settings already in config.txt - don't forget to comment out the 3 lines used for low res mode. When changing from low to high res (or vice versa) you will probably also want to update the bootsplash to suit (see below).

OPTIONAL EXTRA OPTIONS:
++ UPDATE BOOT SPLASH IMAGE
To update the bootsplash put a suitable file into /boot/splash as splash.png - it will be installed automatically then auto reboot the system. 240p and 480p sample files are included in the folder. The bootsplash only displays for less than a second so you may not want to bother with it...

++ USE ORIGINAL EXE - high res only
For high res monitors only you can force use of the original exe rather than the (I)Fix(ed)itFelixJr launcher by creating an empty text file called original.txt in /boot/. ie. /boot/original.txt
NOTE: this setting has no effect when using low res settings.

++ DEDICATED GAME BOARD MODE
To force 'dedicated' mode (auto reboot in case the game crashes or after game exit), create the file: /boot/dedicated.txt

++ USE 5x horizontal scaling (default is 6x) - low res only
Create file /boot/5xscaling.txt

Enjoy! As always any feedback is welcome.
