Gonta!! 2 / Lady Killer Part 2 - Party Time Custom chip 59 = 68000 cpu Custom chip 101 = Arm6 cpu Custom chip 113 = Alpha blending Custom chip 99 = 'Ace' chip (Special alpha blending?) Custom chip 156 = Encrypted ARM cpu Custom chip 102 = Encrypted 68000 cpu Custom chip 55 provides two playfields of 4bpp tiles, with optional rowscroll and column scroll. Some games use two of these to give 4 playfields. Palette banking, tile banking and priority are outside the scope of this chip, and usually differ between games. Some games combine the 4bpp output of each playfield to give an effective 8bpp display. Custom chip 56 is the same as 55 but with on-chip decryption, so encrypted roms can be used. Custom chip 74 is the same as 56 but with different decryption tables. Custom chip 141 is same as 56, but can output up to 8BPP per layer.

TODO: - convert to c++ device - should the decryption functions for the tilemap chips be here too? it seems overall height / width of the tilemaps can be configured somehow darkseal clearly needs 64 rows, whereas other games need 32. width seems configurable in a similar way, with nitroball and lockload needing narrower tilemaps. lockload/dragngun might be a good study case as they run on the same harwdare, and both rely on different behavior. ***************************************************************************/ #include "emu.h" #include "video/deco16ic.h" #include "ui.h" typedef struct _deco16ic_state deco16ic_state; struct _deco16ic_state { screen_device *screen; UINT16 *pf1_data, *pf2_data; UINT16 *pf12_control; const UINT16 *pf1_rowscroll_ptr, *pf2_rowscroll_ptr; tilemap_t *pf1_tilemap_16x16, *pf2_tilemap_16x16; tilemap_t *pf1_tilemap_8x8, *pf2_tilemap_8x8; deco16_bank_cb bank_cb[2]; int use_custom_pf1, use_custom_pf2; int pf1_bank, pf2_bank; int pf12_16x16_gfx_bank, pf12_8x8_gfx_bank; int pf1_colourmask, pf2_colourmask; int pf1_colour_bank, pf2_colour_bank; int pf1_trans_mask, pf2_trans_mask; int pf12_last_small, pf12_last_big; int pf1_8bpp_mode; }; /***************************************************************************** INLINE FUNCTIONS *****************************************************************************/ INLINE deco16ic_state *get_safe_token( device_t *device ) { assert(device != NULL); assert(device->type() == DECO16IC); return (deco16ic_state *)downcast(device)->token(); } INLINE const deco16ic_interface *get_interface( device_t *device ) { assert(device != NULL); assert((device->type() == DECO16IC)); return (const deco16ic_interface *) device->static_config(); } /*****************************************************************************************/ static TILEMAP_MAPPER( deco16_scan_rows ) { /* logical (col,row) -> memory offset */ return (col & 0x1f) + ((row & 0x1f) << 5) + ((col & 0x20) << 5) + ((row & 0x20) << 6); } static TILE_GET_INFO_DEVICE( get_pf2_tile_info ) { deco16ic_state *deco16ic = get_safe_token(device); UINT16 tile = deco16ic->pf2_data[tile_index]; UINT8 colour = (tile >> 12) & 0xf; UINT8 flags = 0; if (tile & 0x8000) { if ((deco16ic->pf12_control[6] >> 8) & 0x01) { flags |= TILE_FLIPX; colour &= 0x7; } if ((deco16ic->pf12_control[6] >> 8) & 0x02) { flags |= TILE_FLIPY; colour &= 0x7; } } SET_TILE_INFO_DEVICE( deco16ic->pf12_16x16_gfx_bank, (tile & 0xfff) | deco16ic->pf2_bank, (colour & deco16ic->pf2_colourmask) + deco16ic->pf2_colour_bank, flags); } static TILE_GET_INFO_DEVICE( get_pf1_tile_info ) { deco16ic_state *deco16ic = get_safe_token(device); UINT16 tile = deco16ic->pf1_data[tile_index]; UINT8 colour = (tile >> 12) & 0xf; UINT8 flags = 0; if (tile & 0x8000) { if ((deco16ic->pf12_control[6] >> 0) & 0x01) { flags |= TILE_FLIPX; colour &= 0x7; } if ((deco16ic->pf12_control[6] >> 0) & 0x02) { flags |= TILE_FLIPY; colour &= 0x7; } } if (deco16ic->pf1_8bpp_mode) { // Captain America operates this chip in 8bpp mode. // In 8bpp mode you appear to only get 1 layer, not 2, but you also // have an extra 2 tile bits, and 2 less colour bits.
