/* Semicom Baryon / Dream World hardware Note: this hardware is a copy of Psikyo's 68020 based hardware, the Strikers 1945 bootleg has the same unknown rom! It isn't quite as flexible as the original Psikyo hardware by the looks of it, there are various subtle changes to how things work, for example the tilemap sizes and missing transparent pen modification. This makes it rather hard to merge with psikyo.c and it should probably be left separate.

In this case the tilemap size registers from the original psikyo hardware are set to be the alternate tilemap size, however that doesn't make sense in the context of the data in RAM, which doesn't appear to wrap properly anyway, again, it's likely this is just how the game is. Furthermore the BG test in the test menu indicates that it tests alternate tilemap sizes, but doesn't even write to the register, probably a leftover from hardware development as the test menu is mostly incomplete. All: sprite priority, the original psikyo.c HW has sprite<->tilemap priority but we don't support it here, does the clone HW support it? All: sprite zooming, again the original psikyo.c HW supports this, but we don't support it here. The Strikers 1945 bootleg in psikyo.c doesn't appear to support it properly either, so it might be missing on these clone boards. */ #include "emu.h" #include "cpu/m68000/m68000.h" #include "sound/okim6295.h" #define MASTER_CLOCK 32000000 class dreamwld_state : public driver_device { public: dreamwld_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } /* memory pointers */ UINT32 * m_bg_videoram; UINT32 * m_bg2_videoram; UINT32 * m_vregs; UINT32 * m_paletteram; UINT32 * m_spriteram; UINT32 * m_workram; /* video-related */ tilemap_t *m_bg_tilemap; tilemap_t *m_bg2_tilemap; int m_tilebank[2]; int m_tilebankold[2]; UINT32* m_spritebuf1; UINT32* m_spritebuf2; /* misc */ int m_protindex; }; static void draw_sprites( running_machine &machine, bitmap_t *bitmap, const rectangle *cliprect ) { dreamwld_state *state = machine.driver_data(); const gfx_element *gfx = machine.gfx[0]; UINT32 *source = state->m_spritebuf1; UINT32 *finish = state->m_spritebuf1 + 0x1000 / 4; UINT16 *redirect = (UINT16 *)machine.region("spritelut")->base(); while (source < finish) { int xpos, ypos, tileno; int xsize, ysize, xinc, yinc; int xct, yct; int xflip; int yflip; int colour; xpos = (source[0] & 0x000001ff) >> 0; ypos = (source[0] & 0x01ff0000) >> 16; xsize = (source[0] & 0x00000e00) >> 9; ysize = (source[0] & 0x0e000000) >> 25; tileno = (source[1] & 0x0000ffff) >>0; colour = (source[1] & 0x3f000000) >>24; xflip = (source[1] & 0x40000000); yflip = (source[1] & 0x80000000); xinc = 16; yinc = 16; if (xflip) { xinc = -16; xpos += 16 * xsize; } if (yflip) { yinc = -16; ypos += 16 * ysize; } ysize++; xsize++; // size 0 = 1 tile xpos -=16; for (yct = 0; yct < ysize; yct++) { for (xct = 0; xct < xsize; xct++) { drawgfx_transpen(bitmap, cliprect, gfx, redirect[tileno], colour, xflip, yflip, xpos + xct * xinc, ypos + yct * yinc, 0); drawgfx_transpen(bitmap, cliprect, gfx, redirect[tileno], colour, xflip, yflip, (xpos + xct * xinc) - 0x200, ypos + yct * yinc, 0); drawgfx_transpen(bitmap, cliprect, gfx, redirect[tileno], colour, xflip, yflip, (xpos + xct * xinc) - 0x200, (ypos + yct * yinc) - 0x200, 0); drawgfx_transpen(bitmap, cliprect, gfx, redirect[tileno], colour, xflip, yflip, xpos + xct * xinc, (ypos + yct * yinc) - 0x200 , 0); tileno++; } } source += 2; } } static WRITE32_HANDLER( dreamwld_bg_videoram_w ) { dreamwld_state *state = space->machine().driver_data(); COMBINE_DATA(&state->m_bg_videoram[offset]); tilemap_mark_tile_dirty(state->m_bg_tilemap, offset * 2); tilemap_mark_tile_dirty(state->m_bg_tilemap, offset * 2 + 1); } static TILE_GET_INFO( get_dreamwld_bg_tile_info ) { dreamwld_state *state = machine.driver_data(); int tileno, colour; tileno = (tile_index & 1) ?
