>games not validated for correctness under software emulation for detecting these types of edge cases prior to shipping.
Did they have software emulation for that hardware at the time the game was written?

I understand it was less practical to do this for say, the NES or SNES. But it should have been done for the GBA. It's not just important for future hardware to be able to easily emulate GBA games, it also protects against product refreshes breaking games, something that plagued quite a few classic Game Boy games as newer models came out and fixed bugs in the older models.
