Inspired by this thread: https://gbatemp.net/threads/custom-firmware-for-sega-flashback-2018.523590/

Was wondering if there is any progress for making it possible to add games easily or replace the firmware? The only mentions that I have heard is that you would need to desolder the flash chip, place it into a programmer, flash the games you want, and then solder it back in. The process is very time consuming, and overtime, the pads would start to deteriorate. Looking for answers here.

Reviving this thread real quick to give anybody some clues on what the hardware is. It uses a Monkey King 3B SoC, which is supposedly an AllWinner A13 or some other chip, since most of these from DMC are mostly based on AllWinner.

I think all Legends and Genesis Flashback devices from 2018 to 2020 used same rock monkey chip. I'm guessing Pico can be installed. There's no sd card so hence de solder chip.

How can a Pico be installed into these?

This device is not based in Rockchip (Monkey King 3.6/RK3036 and RK3066) or Allwinner SoC, it uses a custom chip like the one running on the Atgames Atari Flashback Portable. I don't think anyone was able to access this SoC besides using a reader to extract the Flash Memory contents.

Oh ok thx. Can you send me Pico (even if its beta) for Legends Flashback 2018 50game so i can hack update/software update it to play 32x roms.

Be sweet to add screen and battery 🔋 to unit and replace board with Legends Flashback 2018 50game board to this unit or maybe put in Ambernic Sega unit. I simply cannot play anything without rewind feature anymore lol.

    as to you

    How do you know if the night will be good when you're asleep

    because i didn't say i was asleep

    Even my mum slept on that uremum
  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think

    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
