This is a compilation of the hardest sections completed so far, of the much harder arcade version of this game (Completed the Genesis port recently). The 1P Rom which does not let you respawn right where you died, but sends you back. Stage 4 boss is currently very hard. This is from my first 1 hour 20 minutes with the game and completing 3 stages, getting to the stage 4 boss.
For the second checkpoint shown, I show the death since that was far enough to activate the next checkpoint for the stage. Luckily I did not have to destroy both of those blue ships. That was a tough checkpoint. The hardest checkpoint so far was the two bosses shown at the end.
As usual, I am doing most checkpoints with no starting power ups since that is the price you pay for dying in these checkpoint to checkpoint arcade shooters. Based on how hard the Genesis port was at the end, Im assuming this version will be much more insane later on.
