Along the same lines, maybe two outputs for monitor rotation: 1 for rotating it horizontal, another for rotating it vertical

Well that would be needed I guess, could be handy for testing purposes, and simple trouble shooting. The chip I will be using has versions that have over 600 I/O pins. The only thing is that pins that is used for more unusual things, has to have support from another board with the extra stuff needed. At this point it looks like I could place two 2x20 headers on the board for dedicated I/O stuff. Would that be enough? Any one that want to count up things?

What should that be used for? Any good examples?

P1
4 directional inputs
6 action inputs
1 P1 Start input
1 P1 Coin input

12 inputs
P2
4 directional inputs
6 action inputs
1 P2 Start input
1 P2 Coin input

12 inputs
P3
4 directional inputs
4 action inputs
1 P3 Start input
1 P3 Coin input

10 inputs
P4
4 directional inputs
4 action inputs
1 P4 Start input
1 P4 Coin input
---
10 inputs
1 Exit Input
1 Pause Input
TOTAL: 46

Well that could be added. My only concern is that the main board doesn't get cluttered with odd stuff. So it has to be added in a manageable way. And things that belongs in groups, is best managed if they isn't split up on several connectors. 2x20 headers could be one way to add other boards with hard drive cables. Any one else that know ready made cables that would be good to use?

Will there be any sort of software interface to assign all this in each game, similar to the current MAME settings menu? For Jamma boards that don't have on board light gun hook-ups (for example) will it be able to to tell there's a light gun present? I'm how you'll be able to interface controllers with the Jamma boards. Interface and moving through the roms will also need to be somewhat configurable, perhaps by using the file structure present on the SD card.

I would like to stay away from software interfaces as much as possible. One way to avoid this would be to use dedicated I/O. With this new board we don't have to stay compatible with any PC software. The only thing is the cabinets and the old games.
How to manage game switching is something that has to come from actual needs. One important need is to be able to switch games without adding anything extra to a original cabinet. Any other thoughts about that is welcome.
I would say that we use dedicated I/O for light guns.

Case in point, MAME displays vector like crap. Getting vector to look remotely decent on anything but a vector monitor is a trick. AAE is a passable solution but is very resource intensive (not to mention a completely dead project), is this project going to be able to address this? This isn't a have to have to but surely would be a nice to have.
I'm down to test and hope you are able to produce a great product.

Well I wont make any raster conversion of old vector games, thats for sure. If it would be possible to convert CRT's to vector monitors, than I could add support for that. If someone would like a conversion, they wold have to convert the vector-signals outside the board :lol Maybe I will do some conversion for testing games. But I think the real stuff is better.
