Black Tiger Beta MiST(er)
Added 2019-11-24 21:24:33 +0000 UTCAs you requested on last month's poll, I have worked this month on Black Tiger (beta files here). This is an awesome RPG-ish arcade game from 1987. Manuel Astudillo had sent me this PCB too as he is very fond of this game. Thanks Manuel!
Technically speaking, the game uses the same object (sprite) engine than 1943 as well as the same microcontroller unit (Intel 8751) for protection. It breaks apart from other CAPCOM cores in:
1. The RAM memory holding the scroll tile map is four times larger than any other game so far. It is even banked!
2. Most devices are mapped to the Z80 using I/O ports instead of memory addresses
3. The sound CPU controls the time using the Yamaha timers, instead of a fixed interrupt from the PCB (Tiger Road also does it this way)
4. A more complex background/object overlapping rule is used
I will write a dedicated post about point 4. It is an interesting feature of many arcades.
About game play, it shares some elements with Willow. Check out the shop and the items you can buy, for instance. The flying demon resembles the one in Ghosts'n Goblins too. By the way, the game in MAME feels much faster. The speed in MiST(er) should be the correct one.
And the next game will be Side Arms!

Can you mention an example I can test? I did reduce the FM gain in Ghosts’n Goblins because it was distorting with the map music. I haven’t noticed distortion in other titles with my speaker set (using the analogue output)
