First off, computers or other machines which use/have keyboards) are started in an emulated keyboard state. This means that the UI is locked out so you can fully use the keyboard without the UI keys being detected and overtaking as you type. By default, SCROLL LOCK is the key that toggles this off and hitting that will allow the UI to take priority. You can start MAME with "ui_enable", which starts MAME with UI as the priority. You can find this in the UI by starting MAME --> Configure Options --> Advanced Options --> Look for "Input Option" area and there should be "UI Enable". Toggle this ON and it will start emulation as it does with non-keyboard machines.

Regarding Odyssey 2 graphical and other issues, most games work fine and there are a few which do not work as expected. It might be better to handle this with a flag for the machine stating that the graphics are not 100%.

You should keep your BIOS separate and put all your software in another folder (odyssey2) for example, somewhere in your rompath. Also, if you expect to use anything from the softlist, it is expected to have the same game short name (qbert, bees, kccrazy). Otherwise, use the file manager and load them however you wish.

From what you've detailed, I know a few are valid but I haven't tested them all. I'll attempt to look at your concerns and tidy them all up in to a bug report on http://www.mametesters.org Having a report doesn't guarantee any listed issues will be fixed soon, but it does keep them logged for others to see.
