The lightgun hardware in these two (as well as the eerom and calibration process) looks identical. The game has 4 separate layers of graphics - one 64x64 tiled scrolling background plane of 8x8 tiles, a similar foreground plane, a sprite plane, and a text plane with character definitions held in ram. The sprites are 16x8 tiles aggregated through a spritemap rom into 64x64 zoomable sprites. The main difference is that Operation Thunderbolt uses only a single 68000 CPU, whereas Spacegun has twin 68Ks. (Operation Thunderbolt has a Z80 taking over sound duties, which Spacegun doesn't.) custom ICs ---------- TC0020VAR sprites?? TC0050VDZ x3 sprites??

The ROTARY input controls the separation between left and right players, the game adjusts the values written to the external volume controller depending on it. Possible values are: 111 (max) 011 (high) -01 (med) --0 (low). It's a rotary control so only one bit is supposed to be low. (Changed set led output to proper output port. --HowardC) - The outputs I'm turning on are actually the gun solenoid outputs, which would rattle the gun while firing. - BM, 060108 - The original flyer for this game has screenshots which clearly show the background is 4 pixels to the left on several game stages (you can see the edge of sprites overlapping past the right edge). Therefore I do not believe the TC0100SCN problem mentioned above actually exists. The current emulation appears to be accurate. Stephh's notes (based on the game M68000 code and some tests) : 1) 'othunder', 'othundrj' and 'othunduo' - Region stored at 0x03fffe.w - Sets : * 'othunder' : region = 0x0003 * 'othundrj' : region = 0x0001 * 'othunduo' : region = 0x0002 - These 3 games are 100% the same, only region differs ! - Coinage relies on the region (code at 0x000db2) : * 0x0001 (Japan) and 0x0002 (US) use TAITO_COINAGE_JAPAN_OLD * 0x0003 (World) and 0x0004 (licensed to xxx) use TAITO_COINAGE_WORLD - Notice screen only if region = 0x0001 - According to the manual, DSWB bit 6 determines continue pricing : PORT_DIPNAME( 0x40, 0x40, DEF_STR( Continue_Price ) ) PORT_DIPSETTING( 0x00, DEF_STR( 1C_1C ) ) PORT_DIPSETTING( 0x40, "Same as Start" ) However, many conditions are required to make it work due to code at 0x00e0c4 : * region must not be 0x0001 * "Allow Continue" Dip Switch must be set to "Yes" * coinage must be 2C_1C for both slots This is why this Dip Switch has NO effect in the following sets : * 'othunder' : coinage can't be 2C_1C for the 2 slots (coin B) * 'othundrj' : region = 0x0001 - DSWB bit 7 ("Language") affects parts of the texts (not the ones in "demo mode") but the voices are always in English regardless of the region ! 2) 'othundu' - Region stored at 0x03fffe.w - Sets : * 'othundu' : region = 0x0002 - Comparison with 'othunder' : * slightly different code at 0x023c4c * additional data from 0x023eee to 0x0240ed (0x0200 bytes) * same other notes as for 'othunder' TODO: ----- - With the correct clock speed of 12MHz for the 68000, garbage graphics remain over the Taito logo on startup. This seems to be a bug in the original which would have no effect if our timing was 100% right. The interrupt handling should be quite correct, it's derived straight from the schematics and PAL dump. The current workaround is to make the 68000 run at 13MHz. Lowering below 12MHz would work as well, and possibly be closer to the real reason (wait states slowing the CPU down?) - The "FIRE!" arrows pointing to padlocks are not in perfect sync with the background scrolling. Should they? - The quality of the zoomed sprites could probably be better. Drawing them as made by 16x8 tiles loses precision due to limitations of drawgfxzoom(). - Schematics show a OBPRI output to control sprite priority. This doesn't seem to be used however, and isn't hooked up.
