/*************************************************************************** Xexex (c) 1991 Konami - GX067 Change Log ---------- (ATXXXX03) Hooked up missing memory handler, emulated object DMA, revised IRQ, rewrote the K053250(LVC) effect generator, ported tilemaps to use the K056832 emulation(the K054157 is a complete subset of the K056832), corrected a few K054539 PCM chip misbehaviors, etc. The following bugs appear to be fixed: General: - game doesn't slow down like the arcade IRQ 5 is the "OBJDMA end interrupt" and shouldn't be triggered if DMA didn't complete within the frame. * game speed may not be 100% correct but close to that on the Gamest video especially in stage 6. Xexex is 384x256 which suggests an 8Mhz horizontal dotclock and DMA delay can range up to 32.0us(clear) + 256.0us(transfer). Increase XE_DMADELAY if emulation runs faster than the original or use cheat to overclock CPU 0 if you prefer faster gameplay. - sprite lag, dithering, flicking (DMA) - line effects go out of sync (K053250 also does DMA) - inconsistent reverb (maths bug) - lasers don't change color (IRQ masking) - xexex057gre_1 (delayed sfx, missing speech, Xexexj only: random 1-up note) - xexex057gre_2 (reversed stereo) - xexex065gre (coin up problems, IRQ order) - L1: xexex067gre (tilemap boundary), misaligned bosses (swapXY) - L2: xexex061gre (K054157 offset) - L4: half the foreground missing (LVC no-wraparound) - L5: poly-face boss missing (coordinate masking) - L6: sticky galaxies (LVC scroll bug) - L7: misaligned ship patches (swapXY) Unresolved Issues: - random 1-up notes still pop up in the world version (filtered temporarily) - mono/stereo softdip has no effect (xexex057gre_3, external mixing?) - K053250 shows a one-frame glitch at stage 1 boss (DMA timing?) - stage 3 intro missing alpha effect (known K054338 deficiency) - the stage 4 boss(tentacles) sometimes appears darker (palette update timing?) - the furthest layer in stage 5 shakes when scrolling up or down (needs verification) - Elaine's end-game graphics has wrong masking effect (known non-zoomed pdrawgfx issue) ***************************************************************************/ #include "emu.h" #include "cpu/m68000/m68000.h" #include "deprecat.h" #include "video/konicdev.h" #include "machine/k053252.h" #include "cpu/z80/z80.h" #include "machine/eeprom.h" #include "sound/k054539.h" #include "sound/2151intf.h" #include "sound/flt_vol.h" #include "includes/xexex.h" #include "includes/konamipt.h" #define XE_DEBUG 0 #define XE_SKIPIDLE 1 #define XE_DMADELAY attotime::from_usec(256) static const eeprom_interface eeprom_intf = { 7, /* address bits */ 8, /* data bits */ "011000", /* read command */ "011100", /* write command */ "0100100000000",/* erase command */ "0100000000000",/* lock command */ "0100110000000" /* unlock command */ }; #if 0 // (for reference; do not remove) /* the interface with the 053247 is weird.
