Classic NES controller to pins 21,22,27 Adjusted synclevel for stable picture
…lor bleeding between pixels. Force black on bejond line 240 on PAL.
… NTSC palette. Reverted sync level to 40 (can be adjusted in config.h)
…fig.h. removed duplicate off video levels in emu.h
…he color burst to improve NTSC sync/color detection (incl. new palletes to match). Split PAL and NTSC render schemes. Make sure to use floats and not doubles.
… the sync and made the sync to really match 4.7us (things should be close to spec now)
…e). R-type is now working and many other games have no or less slowdowns
Hi what do you mean by SD card support FAT 8.3 filenames ? sort file names , SD card did work for me |

You have to format the SD card as FAT16 (I am not sure that FAT32 will work but it might) further more you'll need to make filenames no more than 8+3char long ex. "supmario.nes" (I have not tried if it works with longer ones) and lastly make sure that you put the ROMs in the correct folder on the SD card (see the config.h /nonfredo for NES), you'll also need to edit/uncoment the define there (//#define USE_SD_CARD) to enable the SD cards as ROM source (instead of SPIFFs). I noticed that you published videos on these emulators on your youtube channel and pass it along as if you made all the work with no references the true devs... make sure to link to the correct places and give credit where credit is due! |

Could you maybe implement a old ATARI Controller |

Hello, I am working with your ESP_8_BIT project on an ESP32-WROOM-32 board. My goal is to build a dedicated Sega Master System system with PAL composite video, SD card support, and the original Sega Master System 9-pin controller. I have already tested the SMS/PAL video output successfully. I would like to ask if you have continued developing the SMS part of this project, or if you know of any newer fork or modified version that would be a better starting point for a dedicated SMS system. I am also interested in adapting your controller code for the original Sega Master System 9-pin controller. Any advice would be greatly appreciated. Thank you for your work on ESP_8_BIT. |

Hi, Feel free to fork and add other hard wired joysticks. Cheers

Thanks for your reply. I really appreciate it. What we need is a much simpler and smaller version of this project, dedicated only to the Sega Master System emulator. Our first goal is to simplify the project and remove the other emulators and unnecessary features, so that we can have a clean and dedicated SMS version running on an ESP32-WROOM-32. Later, once we reach this simple SMS version, we would like to add the original Sega Master System controller and memory card support. If you remember anything about this project that could help us simplify it, make it dedicated to SMS, or identify parts that can be safely removed, I would really appreciate your advice. Our final goal is a simple Sega Master System system based on an ESP32-WROOM-32, with simple software, the original Sega controller, and a memory card. Thanks again for your help. |

Hi,
First of all thanks a bunch for the huge amount of work you put into this! I enjoyed it a lot :)
I made a few changes that you might want to add (or not)
I added a hard wired classic controller faking HID events and placed most of the code in the IR_INPUT.H file.
I also took the GENERIC_OTHER code to make it possible to access the file menu from the controller by pressing LEFT+SELECT
I also had to adjust the sync level for the NTSC signal to make it stable on my TV but I have only tested it on one TV....
Cheers
