Hello all,

So I installed an HWfly v4 a while back on my OLED and I restarted recently and got a solid yellow which is a firmware error. After this, I updated the firmware and reset the chip.
Now I am getting an infinite training light and no error code after 15 minutes.

Values of C and D are 0.6 which is correct and within range
I can still boot into OFW perfectly fine
Yes, I have checked dat0 multiple times and the C value is 0.6

Any advice would be appreciated

Sure, I'll take some pics soon. Did you want specific places on the board?
Also, do you happen to know what the values of A and B should be?

Not sure which NAND I have, but here are my values.
Tried the firmware on that post, but sadly still have the same issue.

red to ground
3v3 0.43
C 0.67
A 0.46
D 0.67
B 0.41

If I do black to ground I get weird results
C OL
a 0.6
D OL
B OL

Does this indicate C and D problems with my soldering? Why would red to ground seem normal?

Its your C point and 400ish red probe on ground is correct reading. Adapter needs re-positioning.

It was 0.6 when I first installed a while back and it worked fine

  • 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.
