Tagrineth, I'm pretty sure that any problems that occur with an AR4M+ and 1MB games are fairly minor.
Uhm...
OK. SNK's 1MB cartridges, as well as having less memory than Capcom's 4MB, are wired differently.
The AR4M non-Plus was released before Capcom's 4MB expansion, so the 4MB part is wired one way only, for SNK's schematics.
That's why the non-Plus AR4M's only work with very, very few 4MB games, and why you have to add a connection to get X-Men VS SF and Vampire Saviour to work - most others still won't.
The AR4M+ has the wiring for both SNK's 1MB spec and Capcom's 4MB spec, and it auto-switches between the two depending on what's requested, so NOTHING gets broken.
If you try to run SNK's 1MB games using a Capcom 4MB RAM cartridge, not all of them will work correctly.
...there, that should clarify everything. I never said there would be problems with an AR4M+ and 1MB games; in fact I said earlier that the AR4M+ was equipped to avoid the issues that 4MB carts have.
Side note: My AR4M+ arrived yesterday!

So it really does 'auto-switch'? I just presumed the switch was hypothetical and it just managed the RAM correctly.
