Hi! After completing my first romhack for NES Tetris I decided to write a quick guide covering all the changes I made to the original game (I mostly did graphics and color changes... super easy) in case 1) I want to go back to NES romhacking in the future and don't remember anything and 2) anyone may find anything here useful if they want to start romhacking too. I must clarify that this is my first attempt at NES romhacking. This is just a newbie sharing what little knowledge they managed to learn in the process. This being said, let's start! I used the following tools: Mesen : the NES emulator I use. YYCHR : for the graphics (this only changes graphics, not colors! Colors are changed in the emulator) TBLater : needed in some games to change text Lunar IPS : to convert your final .nes file into an .ips file *Note to self: For some unknown reason, if I open this hack in FCEUX the colors look completely different than they do in Mesen. Select the palette "nestopia_yuv"...
