So I was having this really weird issue when playing Wario Land with the Ez-Flash Jr. flashcart in my Gameboy Advance. The game would work fine but when coins (and maybe, other items) appeared on the screen, a mess of glitchy graphics would appear along with the item, such glitchy graphics disappeared when picking up the item.

I was having this issue with firmware version 4, the stable one. I read someone having other issues with Wario Land and Ez-Flash Jr. that were fixed with an MBC5 patch for the game, but that seems to be unrelated to the issues I was having. I post this to let anyone with the same issues know that the "beta" firmware version 5 with the name "Update_FW5_7-31" fixes the glitched sprites issues, note that I haven't mentioned the latest "beta" firmware since it has another issue with the game where it resets to the title screen after the first level. Be warned that this firmware is experimental and should only be applied with a high speed micro SD card (I personally had success with a SanDisk Ultra Class 10 A1 UHS-I 16 GB) since slower cards can brick the flashcart. I'm not going to link the firmware due to it's instability, but it can be easily found with a search engine or inside this forum.

I also wanted to know if anyone experiences similar issues with this game running firmware version 4 in the Gameboy Advance or other consoles.

    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
