Hello, I have been working on a sprite hack of "Yoshi" (aka "Mario &Yoshi") for the gameboy.
I'm 90% complete and have hit a brick wall
. All the sprites were easy to rip and alter, no weird encryption, or tile format, until I reached the last set of sprites I needed to change.
Opening the rom in TileLP, at offset 3800, is a set of sprites for a game over cutscene for game mode A, that changes for every 10 eggs you clear.
There are 2 egg sprite that hatch a mushroom, fire flower, star, ghost, bomb or, fish. There's also a yoshi sprite I haven't found in game yet. All these sprites are positioned in the bottom 6 pixelsof the tile, with the bottom 2 rows of pixels going on top of the tile to the right.
Even after formatting my sprites correctly and inserting them there are still random lines and pixels either the wrong color, or out of place.
I Tried for hours to find a rhyme or reason to it, but to no avail. Any help, advice or pointers would be greatly appreciated.Thanks so much.
