Roms not showing up in the menu.

[markoni985]

After placing the ROMs in the data folder for the appropriate emulator not all of them show up in the menu. I kept the names short, with no spaces. Sometimes if I change names device ends in a boot loop where it tries to format FS. A list of supported ROMs and appropriate names would go a long way.

I would say that most ROMs works only some exotic ones will fail. You only have about 1Mbyte of space to store them (in the internal flash memory) so in principle you can only have a handful of ROMs unless you use a SD card for storage (https://github.com/CornN64/esp_8_bit).

I'll give that a try when once sd card module arrives. I tried deleting SPIFFS using :

include "SPIFFS.h"

void listAllFiles(){

File root = SPIFFS.open("/");

File file = root.openNextFile();

while(file){

  Serial.print("FILE: ");
  Serial.println(file.name());

  file = root.openNextFile();

}

}

void setup() {

Serial.begin(115200);

if (!SPIFFS.begin(true)) { Serial.println("An Error has occurred while mounting SPIFFS"); return; }

Serial.println("\n\n----Listing files before format----"); listAllFiles();

bool formatted = SPIFFS.format();

if(formatted){ Serial.println("\n\nSuccess formatting"); }else{ Serial.println("\n\nError formatting"); }

Serial.println("\n\n----Listing files after format----"); listAllFiles(); }

void loop() {}

I also tried compiling and loading on another computer to make sure there are no hidden temp files affecting the compile process.

And I am still getting:

These games are not supposed to be there. Any idea where is this file structure kept so I can delete it? I have a feeling that the script deletes files but not the file structure. Any way to zero-fill SPIFFS?

Thank you.

Thank you in advance.

One way would be to use the download tool Get the flash_download_tool_v3.8.5 (https://www.espressif.com/en/support/download/other-tools) Hit developer mode -> ESP32 downloadtool Make sure correct com port is selected and hit ERASE button, that will wipe everything on the ESP32

Awesome, that worked. Thank you so much.
