- Add new comments about differences between earlier and later models (nw)
- Remove many old comments based on the earlier schematics and faulty guesswork (nw)
- Remove the undumped and possibly never released "from schematics" BIOS (nw)
- m_regs seems to be too small since R_CNT_HOURS is 4 and it will access m_regs at + 6 - so index 10 would be out of bounds
- device_timer() also checked the alarm latch for the months which is never written and doesn't exist according to the data sheet
* Default FreePlay DSW to 'Off' for the recently added 'grudge' parent set (Free Play doesn't work properly on it anyway)
Leave it to 'On' for the previous set because Coin mode doesn't work properly there
Add a note about (undumped) Majesco Frogger TV game likely being nes_vt
* new clones : Kick Goal (set 2)
and cleaned up driver so that it uses oki mem map etc.
* factory defaults for several esd16 sets so they don't run with bogus values (nw)
* note the regions on the fort2b / fort2ba sets, one is world, the other is korea (nw)
* radica6502: first steps to a sound device, 4-bit adpcm format not understood (it isn't OKI ADPCM)
* fix compile (nw)
* cover your ears or end up in tears (nw)
* prevent Tetris from crashing (nw)
* note about similar issue (nw)
* clearly a sound register (nw)
* more likely a status of something (nw)
* create a device for the io stuff (nw)
