someone said it was like 98% compatibility backporting, but in reality it's more like 60-80%. some games simply don't work. I'm trying ni no kuni with 80 files to backport. couldn't get control to work with 25 or so.

So, is better to keep games not so updated to latest patch, but all bellow 6.72, is no problem to me, most of the time, I don't notice any difference between version 1.0 and version 1.x

bug fixes and dlc usually requires a certain version. one thing I've noticed is that unlike the ps3, the latest update is all you need. some games on the ps3 require you to install every update.

Everyone who has tried has failed with Control. It’s an elusive one. But once 6.72 is stable, I guess back porting it won’t be necessary :)

Has Astro Bot been backported?

Edit: I found a backport, filename says A101, it's only 60-odd meg so I'm guessing it's a fix for the base game rather than the actual 1.01 update backported. If anyone sees/makes a backported update (latest version is 1.03 afaik) please lmk, but for now I'm happily playing the game B-) lot of fun so far.

Cause what is calling "backporting" right now consists of changing a string in ELF/PRX that indicate the minimum FW required to execute them. It works without problems when a title was developed with an SDK lower or equal to, in this case, FW 5.05 or when it doesn't use new functionalities introduced on newer FWs, otherwise it fails.

A real backport instead would consist in replicating the missing functionality on lower FWs or modifing titles' executables to not use those missing callbacks, but still behaving correctly.

I don't see people wasting time dong this king of patching, but I would not be surprised if someone step forward only to prove me wrong, I've seen crazy things done on emulators/consoles...

    because i didn't say i was asleep

  • 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
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
    Karma177 @ Karma177: @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really...
