Hello! I’m a new poster here, though not entirely new to the community. I’ve been working on vertical overlays myself for the past couple of months, and I just launched a website, VerticalArcade.com, to give them a more permanent home. My intent is to try to build it into something of a hub for the community, not just stuff I’m doing. I’ve been chatting with ArsInvictus on Reddit about collaborating in some way, and he looped me in to what you guys have been doing recently (I have been following his thread for quite a while), you guys are doing some great work!
My stuff is currently all in MAME, not Retroarch yet, though I intend to port it over soon. My focus so far has been primarily on American manufacturers and mid-to-late 80s/early 90s games, the heyday of Atari, Bally Midway and others. ArsInvictus has been really helpful and I definitely learned some stylistic ideas from him, and I’m excited to contribute to the growing community around vertical overlays. Anyway, I will keep an eye on everything going on here and hopefully participate in the discussions soon!
