Hello, I like your examples with LVGL. I would like try NES example on ESP32S3 board with 7 inch screen, but I have problem with RAM. There is used too much static memory. Please, could you help me, which defines should be set to lower RAM consuption?

I am getting this error: nes-simulator.elf section .dram0.bss will not fit in region dram0_0_seg

Could you help me please?

I'm very sorry!! I only noticed the issue you posted now!

I haven't tried it on ESP32 yet, but I will do it soon and I will give you feedback on my progress here.

If you want to study simulators instead of lvgl, please take a look at this repository: https://github.com/100askTeam/retro-go-yao-mio

@YobeZhou have you any progress on ESP32 or something else? I've got the same problem with small ram on ESP32, I tried to use PSRAM but failed, the return data was always 0.
