Therefore, it might be another protection device, which sits in the middle
|
||||
between CPU and NMK004.
|
||||
- Protection is patched in several games.
|
||||
- In hachamf it seems that the protection device shares some RAM (fe000-fefff)
|
||||
with the main CPU, and the main CPU fetches pointers from that shared RAM to
|
||||
do important operations like reading the input ports. Some of them are easily
|
||||
deduced checking for similarities in macross and bjtwin; however another
|
||||
protection check involves (see the routine at 01429a) writing data to the
|
||||
fe100-fe1ff range, and then jumping to subroutines in that range (most likely
|
||||
function pointers since each one is only 0x10 bytes long), and heaven knows
|
||||
what those should do.
|
||||
On startup, hachamf does a RAM test, then copies some stuff and jumps to
|
||||
RAM at 0xfef00, where it sits in a loop. We patch around that by replacing the
|
||||
reset vector with the "real" one.
|
||||
update: simulated this,see hachamf_mcu_shared_w() & tdragon_mcu_shared_w() for
|
||||
more info about it.

- Hacha Mecha Fighter bg graphics are completely wrong except at the title screen &

- Hacha Mecha Fighter: mcu simulation *might* be wrong/incorrect (see notes).
|

- Hacha Mecha Fighter: bg graphics are completely wrong except at the title screen &

the level 7.Likely to be a rom issue,the game activates the bgbank

when it is on the above two cases.Also the bomb graphics are wrong when the game
|
||||
is in japanese mode...
|
||||
when it is on the above two cases.
|

- Cocktail mode is supported, but tilemap.c has problems with asymmetrical
|
||||
visible areas.
|

- Music timing in nouryoku is a little off.

Thunder Dragon & Hacha Mecha Fighter shares some ram with the MCU,the job of the latter
|
||||
is to provide some jsr vectors used by the game for gameplay calculations.Also it has
|
||||
the job to give the vectors of where the inputs are to be read & to calculate the coin
|
||||
settings,the latter is in the video file to avoid sync problems.
|
||||
settings,the latter is in a TIMER_DEVICE_CALLBACK to avoid sync problems.
|
||||
To make a long story short,this MCU is an alternative version of the same protection
|
||||
used by the MJ-8956 games (there are even the same kind of error codes!(i.e the number
|
||||
printed on the up-left corner of the screen)...
|
||||
|
||||
Note: I'm 100% sure of the Thunder Dragon vectors because I've compared it with the
|
||||
bootleg sets,I'm *not* 100% sure of the Hacha Mecha Fighter vectors because I don't have
|
||||
anything to compare,infact
|
||||
anything to compare and I don't know if for example an option should be there if you lose a
|
||||
life,but the game looks pretty much hard without it.
