// license: BSD-3-Clause // copyright-holders: David Haywood, Dirk Best /* 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. -- Chips of note Main board: TS68000CP8 TMS34010FNL-40 TMP82C55AP-2 Bt478KPJ35 Palette / RAMDAC Actel A1010A-PL68C (custom blitter maybe?) 2x 8 DSW, bottom corner, away from everything..
