Dinamic / Inder arcade hardware
Mega Phoenix
Hammer Boy
also known to exist on this hardware:
Nonamed 2 (ever finished? only code seen has 1991 date and is vastly incomplete) (versions exist for Amstrad CPC, MSX and Spectrum)
After The War
trivia: Test mode graphics are the same as Little Robin(?!), TMS is very similar too, suggesting they share a common codebase.
PIC16C54 info:
- The PIC has 5 functions:
* Read dip switches (serially connected) [cmd 0x82 0x86]
* Read the two start buttons [returned with all commands]
* Provide 4 security codes. For the dumped PIC those are:
0x4a 0x6f 0x61 0x6e (Joan). Not used by Mega Phoenix. [cmd 0x8a 0x8e 0x92 0x96]
* Watchdog enable. Not used by Mega Phoenix. [cmd 9a]
* Provide PIC software version to the game. This is 0x11 here. [all other cmds]
- Communication with the game is achieved using a 8255 PPI on port C that is
connected serially to the PIC. For port assignments see the code below.
- The game sends an 8-bit command. After each bit, the PIC sends an answer bit.
The start buttons are always bits 2 and 3 here.
- All sent commands look like this: 1ccccc10
- After the command was received, the PIC will send an additional 8 bits
with the result.
ToDo:
- where should roms 6/7 map, they contain the 68k vectors, but the game expects RAM at 0, and it doesn't seem to read any of the other data from those roms.. they contain
a cross hatch pattern amongst other things?
Sound:
- how does banking work? when the irq callbacks happen for each irq level? currently no way to access this because it's a daisy chain setup with the ctc?
- even if i hack that the title screen speech doesn't work properly - is there a timing register like little robin?
I/O:
- Verify when m_ppi_to_pic_command is set and cleared. It's currently guessed but seems to work fine this way.
