Say "BANK(Foo) ; aka BANK(Bar)" to clarify that Foo and Bar share a bank 2019-01-12 20:17:20 +00:00			`ld a, BANK(sCheckValue1) ; aka BANK(sCheckValue2)`
Harmonize engine/{movie, pokemon} with pokegold (renames GetSRAMBank to OpenSRAM) To do: engine/{menus, overworld} 2020-06-17 21:03:38 +00:00			`call OpenSRAM`
Remove all code from main.asm (some labeled INCBINs, like out-of-context graphics, are still present) engine/routines/ stores isolated out-of-context routines as individual files. It might be preferable later to append them to their related engine/ files in unique little SECTIONs, relying on the linkerscript to place them appropriately; or some other organization method. In the meantime, they're now easily findable apart from main.asm's other content. 2017-12-25 00:35:35 +00:00			`ld a, [sCheckValue1]`
