Ares hangs upon playing intro scene

Worth to mention: is the english patched rom, but I tested on ( retroarch - Genesis Plus GX core ) and works perfectly

Isn't replicable with non-patched version MD5: 0D4BC152E7AE70457FA74F593E064403CD24AB72

Won the first battle and returned home. But this is on the Japanese version.

The patched version resets the game even on the initial screen with a girl at the moment when the text should appear. The translated rom works correctly on Emulicious.

It appears that this romhack is broken because it accidentally triggers the little-used "bank shift" functionality within the Sega mapper.

This function is only present in games sized 512Kb using a very specific rom mapper; but this game also is 512kb so we can't rely on size alone to detect this feature.

As bank shift is a specific mapper variant that appears to be rarely used, we should disable bank shift by default, and only enable it for software known to require it: avoiding false triggers like in this scenario.
