Do you have the wrong sonic rom? If you have the incorrect rom, you can get blue screened (though you may be getting blue screened for a different reason). You need the rom from Steam (or an equivalent version) if you have the wrong sonic rom you can get blue screened when loading states from the correct sonic rom. See example code below to test.

import retro

#this env will work with the correct rom but with the incorrect rom will lead to blue screen after a few frames
#env = retro.make(game='SonicTheHedgehog-Genesis', state='GreenHillZone.Act1', use_restricted_actions=retro.ACTIONS_ALL)
#this env will display the game from the start menu even with the incorrect rom
env = retro.make(game='SonicTheHedgehog-Genesis', state=retro.STATE_NONE, use_restricted_actions=retro.ACTIONS_ALL)
env.reset()

for i in range(10000):
    _,_,_,_ = env.step(env.action_space.sample())
    env.render()

Can you provide a screenshot? I might be able to tell if it's the issue @AurelianTactics is describing based on the shade of blue.

So I need a Sonic rom with it's belonging rom states, I'll try.

@YoKoin any luck?

Stuck for 2 hours and can confirm. If you try to download free ROMs (eg from emuparadise) for Sonic the Hedgehog, even if it's the US version, you either get:

1. blue screen
2. messages like 'ERMAHGERD you're getting sued lol' or 'Illegal instruction + some memory address'

So I think the only solution is to buy the game from Steam, as others have commented, but I haven't tried it since I don't want to pay for a game that I never play ... I think I will just test out some algorithms with Airstriker-Genesis.

Summary: Use the same rom and state, locate the state file and move it to the destination file, run:

usr@machine:~$ gzip /home/usr/.local/lib/python3.6/site-packages/retro/data/game/gamestate.(your save format)

Then rename the gzip to: yoursavestatename.state.

Try it in your environment. When you get there everything should work fine with any rom and it's respective savestate.

For me it worked fine, thanks for the advice.
