Atari/Legends Flashback Expansion Builds

[Gamer2020]

I haven't posted in a while but I was wondering if it's possible to overclock the legends flashback 50 games version to the full 1.5ghz?

Hey there @Gamer2020!  I have sure never tried.  @rmr_md was the one who figure out the overclock and by studying what he did I was able to do something similar for the Atari flashbacks.  When I tried anything above 1.2Ghz it was a no-go, and I feel like I saw some comments from way back in early days that 1.2Ghz was chosen because it was pretty stable.  FWIW it seems like most of these have no trouble with 1.2Ghz, but occasionally someone reports instability even at that, which is I assume down to variation in what the individual processors tolerate - and hence the stock clock rate is a sort of least common denominator.  But that may also mean some few could do 1.5Ghz?  I also always wondered if I had used a 2Amp supply (very sure I was using a 1Amp at the time) if I would have had different results.  It's not such an easy experiment, because if it goes wrong it's a sort of major reflash chore, and not sure I even remember how anymore!

Thanks for the response! Im not as technical as most but with patience most of the time I can get it to work I appreciate everything that was done for these systems it definitely makes them way more useful! I tried a 5 volt 2 amp power supply and so far it didn't make any difference in performance I noticed two updates for the legends on archive what's different between them?

There are two - one from May last year and one from December.  The December one adds some updates, here is the text copied from last year's post on what changed:

 

• Added a firmware folder with the firmware backup and additional detailed instructions.
• Added a Jump n' Bump section with levels for the jumping bunnies game.  This is a two-player game.
• Added many Capcm arcade games with box art, thanks to a helpful AtariAge contributer! 🙂  These games are larger and can take quite a while to load from an SD, so wait patiently (20 or 30 seconds I think) while they start.  There are over 500 arcade entries now, and this dramatically increases the "better games" content on the device.  I'm not sure they all play at full speed, but several I tried do.
• Enabled bezels for A26 section.
