lr-mame2003, Rewind Functionality, and Segmentation Faults?
-
Is there a known bug with rewind functionality in lr-mame2003, at least with regard to certain roms?
I've successfully enabled enabled rewind functionality in retroarch.cfg in the arcade folder, but doing so made me unable to launch either R-Type or R-Type 2, although R-Type LEO still worked. I was fairly confident I had the right ROM set (0.78) and have a non-merged set, so I didn't think I had any clone issues going.
I had updated RetroPie-Setup to the latest versions, updated all emulators via binaries, and then have further updated lr-mame2003 from source to take advantage of the latest backports and fixes.
Emulation Station would briefly load the ROM, and then kick me right back out. The error log, whether detailed or not, only showed of relevance a Segmentation Fault in runcommand.sh.
Out of curiosity, I created a per-ROM configuration file to disable rewind (rewind_enable = "false") and tried running R-Type again. R-Type loaded without complaint, and promptly kicked my butt.
No need for rewind to be generally enabled, but I was surprised that a google search didn't reveal anything about this, so thought I would post it here, potentially to help others running into the same issue.

@periodiclogic while I don't know a lot about rewind on Mame, if you're into R-Type this week we're getting our collective butts kicked here, so join us:

A segmentation fault is usually related to accessing memory the application shouldn't - lack of memory, bad memory management, etc. I don't know a lot about this particular feature or how resource heavy it may be. Have you tried it in FBA for instance? It might need to be reported to the lr-mame2003 repository as a bug.

@pjft Well... I'm up to 26,400 points in R-Type, so I don't think I'm going to be challenging anyone other than myself in the ROW!

@periodiclogic Well, there are quite a few hints and tips there, but regardless this is really mostly for fun with the community. :)

That does seem like an emulator bug. Could you please post this report & the log as a new issue in the mame2003 github repository?
