Ok, I've had the Retron 5 since release.
Last night I decided to sit down and play through the entire Contra Hard Corps.
When I started up the system I was at save state midway through the 2nd stage.
However, when I started from the beginning.. the game crashes everytime I get midway through the 2nd stage (Save the lab route)
The game freezes, and crashes to the OS.
This freeze and crashing to the OS has now spread to 2 other games.. Turtles Hyperstone Heist and Castlevania Bloodlines
The funny thing is, they ALL worked before the newest 2.2 patch
