Hi everyone, I have a problem with pfclear (DPC+). When I test in Stella emulator, it's works, but when I test in Atari 2600 console with Harmony Cartridge, isn't work (screen crashed). When I remove pfclear, the game works, but without clear the playfield, I have some problems in screen transitions. Is exist other method to clear the playfield? Thanks
