#142 Powerjoy 84-in-1 (PJ-008) graphic glitches

[Bumm Thirteen]

The Powerjoy 84-in-1 multi-cart ROM seems to mostly work fine (I have the actual cartridge to compare to). However, in at least some of the games (tested in Flappy and Pandamar), invisible graphics show up unexpectedly that prevent movement of whatever "main character" is being controlled by the first player. These invisible graphics act as "physical" barriers that hinder normal gameplay. These invisible sprites or whatever they are do not show up while playing games on the actual Powerjoy 84-in-1 cartridge.
