Hi everyone,

I'm sharing a mod project I've been working on: Saturn Smart Reset Button.
It's based on Seb's Saturn Switchless Mod (2004), but expands it significantly with features like:
  • Multi-BIOS support with bankswitching (2 or 4 banks using A18 and A19)
  • RGB LED feedback for region and BIOS indication
  • Compatible with retail BIOS, region-free BIOS, or the console's original onboard BIOS
  • Supports 29F800, 29F1610, 27C800, and 27C160 programmable ROM chips for multi-BIOS
  • Ported to XC8, compatible with PIC16F630 and PIC16F676
Documentation, wiring diagrams, and precompiled .hex files are available on GitHub:


Feedback is welcome. Let me know what you think.

Important Notice: Fake Repository Alert

Hi everyone,

Just a quick heads-up regarding the SAT-SRB (Saturn Smart Reset Button) project I shared earlier.
It has come to my attention that a fake repository has been published on GitHub by a user named PoojaAldar29, falsely claiming to host the SAT-SRB project. Please be aware that this is not an official or authorized source.

The official and original SAT-SRB repository is published by ELECTROANALOG and can be found here:

or

Thanks for your support, and feel free to reach out if you have any questions or need help with the mod.
