NES emulator failed to save #18

Closed mender5 closed 3 years ago

mender5 commented 3 years ago

Hi, pebri. When I save the NES game ,The game will restart and fail to save. but other simulators can be saved successfully. I used ESP32-WROVER-IB . I don't know why.

Hi @mender5 I can't reproduce your issue, I tried the latest release and it's working. So could you tell me which version did you use and which rom? I tried super mario bros and castlevania rom and it's working.

mender5 commented 3 years ago

Hi @pebri86 Thank you for your reply. I use v2.2-esplay-micro and it happened on all nes rom. When I save the NES game ,It can be saved normally for the first time. But if I do not exit the NES emulation, Save again will fail and the game will restart. The SAV file on sd card size becomes zero. Only delete the sav file can save it again . ESP32-WROVER-IB seems to be 8M PSRAM，I don't know if it's the reason.

Thanks for your report. I can reproduce the issue, and there's a memory leak on the libsnss that handling the block memory for emulator's ram. Wait for the next release soon.

fixed with v2.3 latest release

Hi, thanks for great project. I still have the issue described above on 2.3 firmware I got from makerfabs few days ago. It's not only on nes games. I even reflashed the firmware and it always fail on save.

pebri86 commented 3 years ago

Hi please, downoad the latest release from github and try again. I tried myself and it's fine

bwiklak commented 3 years ago

Unfortunately effect is the same. What else can I check? My Device options say: RetroLauncher v2.3-esplay-micro IDF v3.3-202-gefdddbb25-dirty

Maybe I could debug it somehow? I'm new to ESP32 but I'd like to play a little bit with this device.

pebri86 commented 3 years ago

Did you have a folder named esplay/data/nes on your sdcard? If not then please create manually, same for all other emulation system

bwiklak commented 3 years ago

That was it! Thanks for help. btw, I'd like to play a little bit with this hardware, write some code, maybe a game. I can't figure out if I can connect to the debugging info somehow, do I need a specific additional hardware?

pebri86 commented 3 years ago

Connecting via usb cable will open serial port on the PC, it's either for programming and debugging. You can use esp-idf tools to do both of them without additional hardware

Thanks a lot! Case solved.
