- Emulate direct manipulation of /OE line for read/write mode control.
- Special handling for data polling before a write has completed.
- Allow optional configuration of device to lock EEPROM after each write, as often used by Atari.
- Eliminate the Atari EEPROM interface devices, since their special features have been incorporated into the base device. To continue using old NVRAM files, rename them from eeprom_eeprom to eeprom.
Newer version of Chuka Taisen on older hardware. Commit now to keep other changes and wait for proper color proms.
New Clone Added
--------------------------------------------------
Chuka Taisen (Japan) (P0-025-A PCB) [Pacman70]
Hooked the AY8912 port and rerouted the dip switch there.
All inputs from the test mode are working. Added technical
notes about the hacked code. Flagged the game as IMPERFECT
GRAPHICS due to the bookkeeping is not completely readable
due to the graphics bank hack needed to show the ingame
graphics properly. [Roberto Fresca]
New working machines
--------------------
unknown Italian poker game [caius, AJR, Ivan Vangelista, Roberto Fresca]
Alligator Hunt (World, protected) [Pablo]
from a dead board, howver, this also shows where the region byte is and uncovers that there's an alt. title of Lizard Hunt, maybe that was used for the US region?
Alligator Hunt (Spain, protected) [David Haywood, Darksoft, Morten Shearman Kirkegaard, Peter Wilhelmsen]
data was verified using a 2nd board, only 1 byte changed in the code area, data table is also verified by checksum in the code, and by the unprotected set as reference. This is a good read.
* hp85: added support for optional ROM cartridges. Started optional ROM
sw list (not finished).
* hp85: refactored mapping of opt. ROMs according to cuavas' comments
