Doubtful.
The board's so dense it's really hard to tell anything.
Let's assume for the moment that the sanded-off ROM is actually a 1 MiB 'PROM instead of a 256 KiB one, and the pirates pre-expanded the fixed bank. (In the absence of two 74'08s or 74'00s, this seems likely). So there's actually 1.5 MiB of storage.
There's a 74'574: that holds the bank. Plus a little; D6 and D7 are connected but clearly do something different. The 74'00 and 74'139 almost certainly decode some combination of address lines and the /WR strobe to make a single banking register...
Pokémon Red used the
MBC3. The pirates clearly didn't include an RTC here.
Somehow they must have folded the 2 bits of RAM banking in with the 6 bits of ROM banking. But without any visible changes to the ROM as dumped, I have no idea how they did that. Maybe a re-dump that doesn't assume that $0000-$3FFF is fixed would cast light?
