On hardware 1.05 had the same problem of not showing the player and wasp sprites, so it turns out the MESS regression was actually an improvement :) Anyway, the eventual cartridge release is available in the same thread and works in MAME. I've submitted a PR to replace the nonworking version: https://github.com/mamedev/mame/pull/10478
