MiSTer FPGA Forum

• MiSTer needs to be updated to the latest using the updater script, or manually updating to MiSTer_20200608 or later.
• The VID/PID of your J-PAC/I-PAC (or similar) device
• A USB keyboard to drive the UI initially

1. Plug in your J-PAC/I-PAC into the DE-10 Nano
2. Plug in your USB keyboard into the DE-10 Nano
3. Turn on your MiSTer device
4. From the initial Cores menu, using the USB keyboard, press F12 to bring up the System Settings menu
5. With the USB keyboard, select "Define joystick buttons" and press Enter
6. Press Right on the Player 1 joystick that is connected to your PAC device
7. The "Define buttons" UI will display "Joystick ID: XXXX:YYYY" where XXXX is your VID and YYYY is your PID
   - Example: Joystick ID: d209:0301
8. Write those values down and shut down your MiSTer device

1. Move your MicroSD card to your computer
2. Open your MiSTer.ini file (or download the latest from https://github.com/MiSTer-devel/Main_Mi ... MiSTer.ini)
3. If your MiSTer.ini file has the following variables already defined, please rename them:
   - jammasd_vid (rename to jamma_vid)
   - jammasd_pid (rename to jamma_pid)
4. If your MiSTer.ini file does not have jamma_vid and jamma_pid variables, please add the following:
   

   Code: Select all

   ; JammaSD/J-PAC/I-PAC keys to joysticks translation
   ; You have to provide correct VID and PID of your input device
   ; Examples: Legacy J-PAC with Mini-USB or USB capable I-PAC with PS/2 connectors VID=0xD209/PID=0x0301
   ; USB Capable J-PAC with only PS/2 connectors VID=0x04B4/PID=0x0101
   ; JammaSD: VID=0x04D8/PID=0xF3AD
   jamma_vid=0x04D8
   jamma_pid=0xF3AD

5. Now you need to change the jamma_vid and jamma_pid values to match what the MiSTer "Define buttons" UI told you the VID/PID were for your PAC device above.
   - Example:
   - jamma_vid=0xD209
   - jamma_pid=0x0301
6. Save the changes and place the MicroSD card back in your MiSTer device

1. Turn on your MiSTer device
2. From the initial Cores menu, using the USB keyboard, press F12 to bring up the System Settings menu
3. With the USB keyboard, select "Define joystick buttons" and press Enter
4. Press Right on the Player 1 joystick that is connected to your PAC device
5. Walk through mapping your Player 1 joystick and buttons
6. For Select, I hold P1 Start and Press Left
7. Press Space on the USB keyboard for any keys you do not need (such as mouse buttons)
8. For the Menu 2-button combo, for now I hold P1 Start and Press Right. P1 Start + P2 Start unfortunately causes the "Define buttons" menu to go away (presses ESC), cancelling the configuration
9. Map "Menu OK" and "Menu Back" buttons so you will be able to drive the MiSTer OSD
10. When you have mapped and skipped all keys, you will wind up back at the System Settings menu. You should now be able to control the OSD with your P1 Joystick and Buttons

Im trying to get my MiSTer working with a JVS-PAC2 by https://irkenlabs.com/jvs-pac2/introduction
And this will definitely help, hopefully full support for the JV-PAC2 will be implemented as this will let a lot of people get controls working with a MisTer on their JVS arcade cabinet.

I play Robotron a lot, have had great luck. I think the key is how you setup the right joystick.

I have literally used every button on the Ipac-2, all 32.. Kinda funny

Edit. Sorted now.

In general I'm happy with keyboard mode except that 2p controls don't work in all cores for some reason. I never got the jamma_vid/pid feature in MiSTer to work so I'm stuck like this right now.

caad wrote: ↑Mon Nov 08, 2021 7:25 am I don't recall exactly but it was just in the normal button mapping UI. You want to change the "shifted" output for the joystick direction (up or right, whichever you pick), since with the JPAC, "shifted" means you're holding down 1p start.

Might want to look at the other shifted outputs as well, since by default the outputs for start + buttons 1-6 are different keys. I just set them so they output the normal keys even when shifted.
