Couldn't find rom partition! about nesemu HOT 6 OPEN

I am not sure why your boot looks different (like no sound init and lots more ram available after heap is freed also vid_init done twice?)
Did you use the ESP V1.04 board manager when compiling?
here is my boot text for reference

Hi, thanks for reply. First of all, I had disabled "//#define CONFIG_SOUND_ENABLED" because I had no idea what sound module in your project. 2nd, I am using ESP32 wrover which has 4MB PSRAM built-in. I enabled PSRAM, that is why my free RAM is high. I tried to disabled PSRAM, the problem still the same "Couldn't find rom partition!". My ESP32 module keep rebooting infinitely which show

I had no idea why "vid_init done" init twice. My NES ROM in spiffs has no problem which I downloaded from https://www.emulatorgames.net/download/ and has been used with other ESP32 NES emulator with no problem. Please help to check if my config.ini has any problem below. Can help to double the project code you had uploaded here has any problem? I had also disabled all the control hardware at prior. (I don't have any hardware yet). Thanks!

You can safely enable audio. It can be connected directly to an analog amplifier (with the filter shown in the ascII drawing) to drive speakers. Other than that I do not have a WROVER chip, I used a WROOM.
Changing some of the hardware specific pins for SPI interfaces will most likely not work since it relies on the hardware to make the transfers work.
what about? -> #define CONFIG_SD_CARD
Are you running on the internal EEPROM or on SD card?
You will need to provide the ROMs in either case and setup the text file accordingly...

Thanks for reply again.

1. Tried with ESP32 WROOM module (without PSRAM) - Problem still same. (I had 2 versions on hand)
2. Already enabled sound (#define CONFIG_SOUND_ENABLED) - Problem still same.
3. Tried with SPI pins (18, 19, 23, 5) - Problem still same.
4. Tried with SDCard. Success to read from sdcard. - Problem still same.
5. Currently using SPIFFS. Copied roms.txt and smb1.nes into data folder and upload to SPIFFS (ESP32 sketch data upload using Arduino IDE) - Problem still same.

I think the problem may be due to the library src/nes_rom.c itself. Please advice. Thanks!

Assuming that WROOM and WROVER are compatible (all tho I think that WROVER uses some of its pins to connect to the PSRAM which might influence things for the worse). From what I can tell it seems to have troubles opening the file system on either spiffs or the SD card, so maybe try some example that lists the SD card to get things running there first... the other tip is to make sure you use Arduino 1.8.13 and maybe more importantly ESPlib 1.04... I know newer versions had caused problems in other projects

Thanks for fast reply again.

1. ESP32 board library is v1.04. - Problem still the same.
2. Read from sdcard. Confirmed can read from SDcard. Exactly same error. "Couldn't find rom partition!" - Problem still the same.

Conclusion. - Give up.......
