Yes, I've tried alterring pretty much any GameBoy setting within the config to no luck. It really seems like this shouldn't be a problem, but something is corrupting the graphics somewhere and I don't know where.
Maybe the KDC emulator doesn't really support GB games hacked to convert to GBC games with custom colors.

Have you tried injecting an original GBC game (such SMB Deluxe, Wario Land 3, etc...)?

Considering the OP was able to get other Game Boy games to work but also with graphical issues (specifically mentioning Pokemon Red), I'm inclined to think that whether the game is in color or not has nothing to do with the graphical issues.

Follow up questions on N64 emulation via Kirby's Dream Collection and the Rom fixer tool by @maciek12305

The tool changes the endianness of N64 roms to that required by Kirby's Dream Collection. Does anyone know what endianness that is?

Additionally, is there a format of N64 rom that works. without needing to run the tool?

That is, does Kirby's Dream Collection require big endian or little endian? According to the internet, z64 is (supposed to be) big endian and .n64 is (supposed to be) little endian.

EDIT: In my testing, the tool appears to convert a big endian (.z64) rom to byte swapped. And a byte swapped (.n64) rom to big endian. Oops. I'm thinking some of the incompatibility I'm seeing is from my improper application of this tool.

EDIT2: It looks like what the Rom fixer does is byteswap the rom. This means it should only be used with whichever format is not already compatible with Kirby's Dream Collection.

Hello, I know that this post is old, I followed a tutorial on how to replace the roms of the Kirby Collection game and I did it, I also replaced the layout of the game, I saw a comment that explained in this post that replacing the main.dol with the .dol from the vc folder emulator, when starting the game the emulator of the replaced .dol starts, but I realized that the game does not save the game, my question is, can the problem of saving the game be solved?

    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
