Hello,
I am a Raspberry Pi 4B (RetroPie/RetroArch) user with Sinden lightguns and am looking to try out as many gun games as I can. I have run into a handful of arcade gun games that are either on the fringe of what the Pi can handle or are only currently working in emulators that do not have full lightgun support.
I am curious about the feasibility of adding any of the below games to the FBNeo arcade romset. Here are my experiences with these games using the appropriate ROMs in the various emulators available to me via RetroPie.
Point Blank 2 (ptblank2): This one is handled very well on my Pi 4B by lr-mame2010 (MAME .139), an emulator that has not had much recent development and lacks full gun support. The PlayStation version works well in the PS1 emulators, but I will gladly forgo that version and its load times if I can get the arcade version up and running.
In case it is at all relevant, the arcade version of Point Blank (ptblank) runs great (aside from very low volume) with gun support in lr-fbneo on my Pi.
Time Crisis (timecris): I am unsure of how well the Pi would deal with this one because it seems that the arcade version of this game can't boot properly in any emulator available to me via RetroPie. As above, the PlayStation version works well but is probably not the best version of the game.
Must Shoot TV (shoottv): This one is an unreleased game from the 1990s that was first included in the MAME .226 romset. It does run well in MAME .235 on Pi, but 2-player gun support is missing from that emulator.
The above three games are all .zip only in MAME. Two other games that have been eluding me are
Judge Dredd (jdredd) and
CarnEvil (carnevil), both of which are .zip/.chd games. I don't see any .chd arcade files among the FBNeo romset, so I am not even sure if it is reasonable to ask about these.
The lightgun Judge Dredd game (not jdreddp, which FBNeo
does support) seemingly runs fine in lr-mame2015, which also unfortunately lacks full gun support. Adding insult to injury, the PlayStation version has some issues in the PS1 emulators available to me.
CarnEvil may be a pipe dream on Pi, but I figured I'd still inquire about it. My suspicion is that this one is too demanding for an overclocked Pi 4B, but I can get the .78 and .106 romset versions to boot and run. The .78 version can be tweaked a bit to improve things, but this game has serious performance issues for me. I guess my only hope here is that later MAME versions would handle the game better. However, the newer MAME RetroArch cores fail to even boot the appropriate ROMs from their respective romsets.
