Hey fellas...Please tell me the name of the editing tool of SEGA games ... because there are several rom HACK, as sonic. If possible give me a link to download this tool.Thanks
A Google search for HiSMS will most likely help you find the tool the author used for his Alex Kidd project.
Also, sad to see this project was never finished nor released, as it was basically the equivalent of the HD texture packs I see floating around for N64 and NES, and not techinically a ROM Hack.
Though, to answer those years old questions regarding if NES had an emulator that could so what HiSMS, there IS. It's called HDNes, and I remember seeing screenshots of someone making an HD texture pack for Super Mario Bros using New Super Bros graphics. It was pretty insane.
