Are you sure the ROM file is ok ? Did you run the checksum on the Pi or on your PC ?
The Asteroids ROM I tried is .a52, but even if I still rename to .bin it starts ok.

EDIT: have you tried running the ROM with the standalone atari800 just to check if it works ?

[Chuck_B]

@mitu with the standalone atari800 I get the ATARI COMPUTER - MEMO PAD screen

[mitu]

@Chuck_B That seems to be because the default machine is the 400/800. Use F12 and change the machine to 5200, then restart the ROM.

[Chuck_B]

@mitu done. now I get the same error I get with lr-atari800

[Chuck_B]

i was able to make Asteroids to work with Retroarch on my pc. I copied the atari800.cfg from my pc to my raspberry (editing the bios directories) but the issue remains.
There is something in Retropie that for some reason does not make it to work

[mitu]

@Chuck_B Did you check the ROM, like I mentioned the last time ? Run a checksum calculation, but on the Pi - maybe the copy on your Raspberry Pi is corrupted.

[Chuck_B]

@mitu the ROM is okay. I overwrote it

[Chuck_B]

@mitu I solved it by zipping the roms

[stoogesfan87]

@mitu I have Raspberry pi 400. I have RetroPie 4.8 installed and I have all 5 bios for lr-atari800

@stoogesfan87 Please open a separate topic instead of necro-bumping old topics.
