1st I want to recomment you, if you haven't already, to take a look into theinks IPac2 Guide

@joshrdunstan said in IPAC-2 causes Dual Button Press:

My IPAC-2 is an early version, pre 2015. I note that there is a firmware that allows an IPAC-2 to come up on the pi as 2 peripherals - however I can't figure out how - or if - I can update the firmware. When I hit the update firmware button on WINIPAC (V1) it just says "Download started" but doesn't appear to do anything.

citing Ultimarc

Latest firmware files (ver 1.55) for all 2015-onwards I-PAC, Mini-PAC and J-PAC boards plus all Ultimate I/O boards regardless of date. NOTE: Attempting to upgrade a pre-2015 board which this firmware will render it inoperable.

Hi, I seem to have the issue that's somewhat documented, where the IPAC-2 I have configured in ES on initial startup, is now causing some double button presses where there's a conflict on what is configured in ES and what's configured in retroarch.cfg. It makes most of the games on MAME unplayable. Both the configured joypad input plus the raw keyboard press are being sent to the emulator.

That's because Mame is recieving the "Keys" from the IPac-2 "Keyboard" together with the "Gamepad-Buttons" from the virtual RetroArch-"Retropad". Depending on the mame core you are using, there is either the possibility from within the retroarch-ui to configure the input mame will recieve, or for cores where that is not possible, the only way I am aware of is to configure the Input via the mame menu using either a real keyboard/gamepad and assigning only real kbd keys or gamepad keys to the functions (or by editing the corresponding .ini (edit: <default>.cfg) by hand (via editor of choice).

@ian02293 That link lays out the basics of what you will need to do. But if you want a custom image you will need to make it yourself with art program like Photoshop; or if you need something free try https://www.gimp.org/

Once you have the image you want you will need to export it as, or convert it to, an SVG file-type. Then you just put it into the proper folder as described in that tutorial.

@eckaji Ahh maybe I should have read that before my last post, now it makes sense however there was still the issue with the error however I think I may have solved the problem. Someone suggested instead of 0777 in the chmod commant just use 777 which seems to have solved the issue. I even manually added a Capcom section which worked. I then started fresh using 0777 and immediately got the error. Im about to start again with the 777 just to make sure it was not a fluke LOL
