PSX: GunCon emulation has been implemented, but the horizontal scale is not correct due to resource constraints. You may need to brighten your screen for some games. All SNES Justifier games have been thoroughly tested, except for Lethal Enforcers. You may need to brighten your screen for some games, but most Super Scope games are already bright enough to work well. Darker games, like certain sections of Shooting Gallery, have trouble. NES (Zapper): NES Zapper is currently not working, pending submission of some code to the main MiSTer framework. It requires a certain level of screen brightness in order to detect the CRT beam some consoles’ lightguns were designed for IR tracking or very tight CRT flash timing, which gives the GunCon 2 some trouble. Overall, the GunCon 2 is an accurate and precise lightgun with relatively little jitter. Note that calibration is per-core, so you’ll need to calibrate separately in NES, PSX, the main menu, etc. To confirm, try enabling the core’s lightgun crosshair (if it has one) and moving around the white screen. If this happens, just delete your calibration files from /config. When doing this with the GunCon 2, BE CAREFUL not to calibrate the min and max of the same axis to the same value (e.g., both offscreen) if you do, your MiSTer will divide by zero when applying your calibration, and will crash. (Note: The menu will prompt you to press “Trigger” press “A” instead.) Your goal is to get the most extreme numbers you can without the gun losing sight of the screen. Using the menu, aim at the extreme edges of the screen, then press A on the left side of the gun to calibrate that edge. A lightgun calibration menu should appear. Open the MiSTer OSD and press F10 on a keyboard. Use the 240p Test Suite’s “White and RGB Screen” pattern to display a full white screen. Open a core (e.g., SNES), and load the 240p Test Suite. To calibrate the gun for a particular core, follow these steps: The ideal calibration settings for the gun will vary for each display, and for each core. You should now be able to use your GunCon 2 as a controller on the MiSTer. The USB connector can be plugged into any of your data-capable USB ports (i.e., not the “POWER ONLY” one on the USB hub.) The yellow GunCon 2 RCA connector needs to be connected to the LightGun RCA Adaptor.

Run the downloader script on your MiSTer to keep its main executable and Linux kernel up to date.

an installed copy of the 240p Test Suite for the core you will run.

Optionally, for calibration, you will also need: Additional SCART Cable to attach on MiSTer.a Namco GunCon 2 (compatibles/clones should work).
