Atari 5200 issues

Merry Christmas to all.

I've been collecting and configuring different games for different emulators for a while, and none of them have given me as many problems as the Atari 5200 emulator. After a lot of work and a lot of testing, I've only managed to get the ROMs with a .bin extension to work, but not the ones with a .a52 extension, which are supposed to work.

I work with a Raspberry Pi 3 and the Retropie version is 4.8.

In the case of the .bin ROMs, I get the well-known message 800 CART NOT FOUND IN DB, after which it stays on a black screen, but pressing the A key on the joystick, the game ends up starting and works correctly.
In the case of the .a52 ROMs, the game doesn't load, and after a while it returns to the Retropie screen of the game list. Looking at the runcommand.log, a message of "1756 segmentation fault" appears.
I have carefully read all the posts related to this emulator and followed their instructions, but I can't find the solution. Specifically, I have checked the following:

I have verified that the BIOS files are correctly installed.
I have checked the content of the retroarch-core-options.cfg file
I have tried different collections of ROMS
I have deleted the lr-atari800.cfg file to force its new creation.
I have updated the lr-atari800 core

If I can't solve the execution of the .a52 ROMS, I would at least like the .bin to end up booting without having to press the A key on the joypad. If anyone knows how to solve this, I would really appreciate it.

Thank you very much.

Can you give an example of a .a52 ROM that you found is correct and doesn't boot in lr-atari800 ? Please provide the name and the checsum of the file.

Hi, mitu.

One file dosn´t works is: Activision Decathlon, The (1984) (Activision).a52
The checksum is: db203973df13b071da46d52fdb078a76f4db428d

Thank you.

I checked on my system and using lr-atari800 should start the game, though the checksum I have is different (45f8841269313736489180c8ec3e9588) than yours. I also tried a different game (BerZerk) and it started without issues.

Make sure you're using the latest lr-atari800 and remove again $HOME/.lr-atari800.cfg. I don't think the latest version of the core uses a .cfg file anymore, but just delete it for good measure.
