Need someone to adapt jsmsx or blue msx emulator (both made with javascript) integrating d-map buttons and fire buttons

Need someone to adapt jsmsx or blue msx emulator (both made with javascript) integrating d-map buttons and fire buttons so i can play it on my ipad. Just need to remap arrow buttons and other buttons like spacebar or return to look like the image below. I want to avoid releasing a site that people still needs to use keyboard to play. There is zanac game for ios implemented that way on appstore...
