0.153 [Rockman, Roberto Fresca, David Haywood]


WIP:

- 0.153: Rockman (from AUMAP) added 'Cuatro en Linea' (System Compumatic 1991). Improvements to 4enlinea driver [Roberto Fresca]: Hooked preliminary HCGA controller in CGA mode (we need proper UM487F device emulation). Added documentation and findings after some analysis. Fixed documentation and confirmed the AY-8910 clock. Adjusted the initial screen parameters according to the HCGA controller programmed registers and improved the way the graphics are drawn. Now the text is readable. Hooked a status handler for the HCGA controller (for now, simulating the state). Improved the memory map fixing the RAM amount and offset, and added the correct offset for the HCGA status. Also hooked 2 debug handlers on ports e000-e001 that spit some random graphics after 30 seconds of the game execution (clue to figure out). More documentation, traces and reverse-engineering. Added custom CM3080 circuitry. Added player 1 & 2 inputs, connected to both AY-3-8910 ports (traced on real hardware). Added info about the PCB connectors [Roberto Fresca]. Improved video rendering a little [David Haywood]. Minor fixes. Added proper CGA device. CPU logic is quite off tho. Added vblank bit 7 hook-up [Angelo Salese].

- 3rd April 2014: Roberto Fresca - David Haywood hooked a second VRAM on Cuatro en Linea. Now we can see the 'interlaced' graphics. Respect to the rest, not much more improvements... Seems that *every* (data/address/switches/coins/etc) is passing through the big FPGA (ES2 9046). Also each time I try to disassemble the (bad called) audio CPU program, I end the attempt totally stressed. A lot of non-sense routines, checksuming empty offsets segments among other obfuscated things. The good thing is that thanks to Rockman from AUMAP, we're documenting the custom IC's and their peripheral circuitry. Well, here the (even/odd) fixed interleaved graphics.

- 27th March 2014: Roberto Fresca - Thanks to the AUMAP people (who contributed with a lot of spanish sets before), we have a new game dumped. This is Cuatro en Linea, and it's running in a very rare and complex platform with 2x Z80 (one for audio), 1x AY-3-8910 for sound, 1x UM487F (HCGA controller) and 3 unknown custom ICs. These custom ICs are: 1x ES2 CM3080 (unknown DIP-18 IC), 1x ES2 9046 (unknown PLCC-84 IC) and 1x 8952 CM 32 (unknown DIP-40 IC). We're trying to reverse them. If someone knows something about, please contact me through the contact page, or just post on Mameworld Forums. Graphics are using a bitmap mode that seems way complex. Some days ago, David Haywood sent a preliminary driver, and I joined to see if we can improve the emulation. The system is using a HCGA controller (UM487F) that has a UM6845R embedded. So I reversed the code to see how this monster is set. There is not much, but we passed from this. Update: Playing with the UM487F status register, got an overflow, that allow me to know our hero (see picture).
