Long loading times with MAME2003+ on 2DS/3DS

Hi everyone,

since RetroArch 1.9.1 the MAME2003+ core takes unbearable long to load any game ROM. I tried a few smaller ones like Klax, Wonderboy and Enduro Racer - all the same. I’ve tested these on a New 2DS and New 3DS console also with the same result. Searching for this issue on the web did not lead to any solution. Apparently, I’m the only one who’s having this problem (or at least noticed it). Is there a secret setting or anything else I’m missing?

Yes, the loading time for MAME 2003 and 2003+ are unbearably long even on the latest 1.9.14 build. Also previously in “Options” menu (under RetroArch “Quick Menu”) of these cores, I can find an option called “Control mapping”. This option is useful because when I set it to “digital”, I can use both D-pad and analog stick, otherwise I can only use D-pad. Now this option is nowhere to be found. In MAME 2003+ core, D-pad and analog stick are both available by default, but in MAME 2003 core, I cannot find a way to use analog stick.
