Your project seems to me very good but too close to zelda 3 redux version which proposes to keep also the original menu of the objects, there are several patches in zelda 3 redux with original style menu or a new object menu there are some patches which are optional.
For example the redux patch gives hair close to the link drawing on the cover and the Japanese notice, there is an optional patch to make the hair pink but the problem of wanting to keep this link as the original does not merge because of color changes with some characters like uncle with black hair and are purple in the original without redux.
I think it would be cool to keep the experience of the graphics identical to the original while keeping your ideas in mind, I just wish you would restore the censored elements of the western versions.
The game has been released in several versions.
zelda 3 usa , zelda 3 pal english , zelda 3 canada , zelda 3 pal french and zelda 3 pal german.
Can you make your patch compatible with all these versions moreover some translate the USA version which is in 60 hrz in their language because not translated into Spanish or Portuguese or other European language.
You will find information on this page about the different versions of zelda 3 on snes. https://tcrf.net/The_Legend_of_Zelda:_A_Link_to_the_Past
Thank you in advance for your work.
