Well at the end of the day, a lot of the emulators/programmes etc. are opensource anyway. These can easily be altered for testing out a more unified keyset. People can then download the modified versions & see which one works the best for them.
If the unified version works the best, then the developers would be welcome to start using it. If not then nobody's really lost out on anything & we can carry on as is.
Facts:
Linux development has become easier, due to unified projects. Just look at how far Linux has progressed within the last 2-3 years thanks to the developers setting standards. A lot of study has already been undertaken in this matter & it would be silly to ignore it.
A unified keyset will help to break down the language & geographic location barriers between the different 2x communities.
A unified key set will make it easier to test out programmes written in different languages. This will speed up development by letting more users bug test new software for developers. It will also give users more programs to play around with.
1) How many people have played Snes game's written in Korean without any hassle, due to knowing that it uses the same keys & layouts for the game as nearly every English Snes game.
2) Over the last day or so, I've managed to sign up for the Spanish forum, post & edit without any hassle even though I only know about 2 words in Spanish. This is because I'm used to the layout of the forum software & I can easily get by without knowing what any of the words say at all.
It will make the need for language translation of software less urgent, allowing developers to concentrate on coding the fun features that they want to add.
They will also save coding time, by all the most important key's needed for the program being setup & mapped out for them.
Personaly.. I think that it's well worth the effort.
If we never try, then we'll never know
p.s Ryo's menu is great by the way & It seems to work spot on without the scan feature. Will be near perfect once it stops screwing with the tv-out
