Check this Reddit thread for the X-Men vs SF glitch which I and others have been able to repro with multiple different AR carts, but not the official 4MB RAM carts. I also personally had trouble with all ARs I tried when playing Alpha 3 for extended periods.
Also see the the links in the comments to some people doing comparisons with Metal Slug on the official 1MB vs 4MB AR cart, seems the latter actually causes more slowdown (for some reason, since the game was designed for the 1MB).
TL;DR this cart doesn't exhibit those issues, and also supports in-game cart saves like the official backup cart, i.e. without having to boot into a menu.
Thanks. Im definitely gonna keep that one on my radar.
Also I wonder if the one I have is the same one you guys are talking about. I dont think I ever had any issues and ive had mine for like 12 years now. I'm check and see if i can replicate the problems youre having.
i feel like mine does have a switch for exactly that. im gonna go check
Edit: checked last night and this is indeed the same as everyone elses. Now that I think about it, my main ram cart back then was a 2 in 1 that had a switch. Maybe thats why I dont remember ever having problems.
