/*************************************************************************** World Grand Prix (c) Taito Corporation 1989 ================ David Graves (Thanks to Richard Bush and the Raine team for their preliminary driver.) It seems likely there are a LOT of undumped versions of this game... If you have access to a board, please check the rom numbers to see if any are different from the ones listed below. ***** World Grand Prix runs on hardware which is pretty different from the system Taito commonly used for their pseudo-3d racing games of the time, the Z system. Different screen and sprite hardware is used. There's also a LAN hookup (for multiple machines). As well as a TC0100SCN tilemap generator (two 64x64 layers of 8x8 tiles and a layer of 8x8 tiles with graphics data taken from RAM) there's a "piv" tilemap generator, which creates three scrollable row-scrollable zoomable 64x64 tilemaps composed of 16x16 tiles. As well as these six tilemap layers, there is a sprite layer with individually zoomable / rotatable sprites. Big sprites are created from 16x16 gfx chunks via a sprite mapping area in RAM. The piv and sprite layers are rotatable (but not individually, only together). World Grand Prix has twin 68K CPUs which communicate via $4000 bytes of shared ram. There is a Z80 as well, which takes over sound duties. Commands are written to it by the one of the 68000s (the same as Taito F2 games). Dumper's info (Raine) ------------- TC0100SCN - known TC0140SYT - known TC0170ABT - ? TC0220IOC - known TC0240PBJ - motion objects ?? TC0250SCR - piv tilemaps ?? [TC0280GRD was a rotatable tilemap chip in DonDokoD, also 1989] TC0260DAR - color related, paired with TC0360PRI in many F2 games TC0330CHL - ? (perhaps lan related) This game has LAN interface board, it uses uPD72105C. Video Map --------- 400000 area is used for sprites. The game does tile mapping in ram to create big sprites from the 16x16 tiles of gfx0. See notes in \video\ for details. 500000 area is for the "piv" tilemaps. See notes in \video\ for details. TODO ==== Offer fake-dip selectable analogue steer Is piv/sprite layers rotation control at 0x600000 ? Verify y-zoom is correct on the stages that use it (including Wgp2 default course). Row zoom may be hard to verify, but Wgp2 course selection screen is probably a good test. Implement proper positioning/zoom/rotation for sprites. (The current sprite coord calculations are kludgy and flawed and ignore four control words. The sprites also seem jerky and have [int?] timing glitches.) DIP coinage Wgp --- Analogue brake pedal works but won't register in service mode. $28336 is code that shows brake value in service mode. $ac3e sub (called off int4) at $ac78 does three calcs to the six AD values: results are stored at ($d22 / $d24 / $d26,A5) It is the third one, ($d26,A5) which gets displayed in service mode as brake. Wgp2 ---- Piv y zoom may be imperfect. Check the up/down hill part of the default course. The road looks a little odd. Sprite colors seem ok except smoke after you crash. (And one sign on first bend of default course doesn't go yellow for a few frames.) [Used to die with common ram error. When CPUA enables CPUB, CPUB writes to $140000/2 - unfortunately while CPUA is in the middle of testing that ram. We hack prog for CPUB to disable the writes.] ***** [Wgp stopped with LAN error. (Looks like CPUB tells CPUA what is wrong with LAN in shared ram $142048. Examined at $e57c which prints out relevant lan error message). Ended up at $e57c from $b14e-xx code section. CPUA does PEA of $e57c which is the fallback if CPUB doesn't respond in timely fashion to command 0x1 poked by code at $b1a6. CPUB $830c-8332 loops waiting for command 1-8 in $140002 from CPUA. it executes this then clears $140002 to indicate command completed. It wasn't clearing this fast enough for CPUA, because $142048 wasn't clear:- and that affects the amount of code command 0x1 runs. CPUB code at $104d8 had already detected error on LAN and set $142048 to 4. We now return correct lan status read from $380000, so no LAN problem is detected.] Code Documentation ------------------ CPUA ---- $1064e main game loop starting with a trap#$5 Calls $37e78 sub off which spriteram eventually gets updated Strangely main loop does not seem to be synced to any interrupt. This may be why the sprites are so glitchy and don't seem to update every frame. Maybe trap#$5 should be getting us to a known point in the frame ?? $21f4 copies sprite tilemapping data from data rom to tilemap area then flows into: $223c code that fills a sprite entry in spriteram [$12770 - $133cd seems to be an irregular lookup table used to calculate extra zoom word poked into each sprite entry.] $23a8 picks data out of data rom and stores it to sprite tile- mapping area by heading through to $21f4. (May also enter sprite details into spriteram.) It uses $a0000 area of data rom. (Alternate entry point at $23c2 uses $90000 area of data rom.) $25ee routine stores data from rom into sprite tilemapping area including the bad parts that produce junk sprites. It calls interesting sub at $25be which has a table of the number of sequential words to be pulled out of the data rom, depending on the first word value in the data rom for that entry ("code"). Each code will pull out the following multiple of 16 words: Code Words Tiles Actual data rom entry 0 1 4x4 [same] 1 2 8x4 [same] 2 4 8x8 [same] 3 3 12x4 [same, see $98186] 4 6 12x8 5 9 12x12 [same] 6 2 4x8 [WRONG! says 8x12 in data rom, see $982bf] 7 6 8x12 [WRONG! says 4x8 in data rom] 8 1 (2x2)*4 [2x2 in data rom] (copies 12 unwanted words - causing junk sprites) $4083c0-47f in sprite mapping area has junk words - due to code 7 making it read 6*16 words. 0x60 words are copied from the data rom when 0x20 would be correct. Careless programming: in the lookup table Taito got codes 6 and 7 back to front. Enable the patch in init_wgp to correct this... I can't see what changes. I'm guessing sprites may be variable size, and the junk sprites mapped +0x9b80-9d80 are 2x2 tiles rather than 4x4. If we only use the first 4 tilemapping words, then the junk sprites look fine. But their spacing is bad: they have gaps left between them. They'll need to be magnified to 2x size - the pixel zoom value must do this automatically. This ties in with the lookup table we need to draw the sprites: it makes sense if our standard 4x4 tile sprite is actually 4 2x2 sprites. But what tells the sprite hardware if a sprite is 2x2 or 4x4 ?? Data rom entry -------------- +0x00 Control word (determines how many words copied to tilemapping area) +0x01 Sprite X size [tiles] (2,4,8 or 12) +0x02 Sprite Y size [tiles] (2,4,8 or 12) +0x03 sprite tile words, total (X size * Y size) on... The X size and Y size values don't seem to be used by the game, and may be a hangover from the gfx development system used. Data Rom -------- $80000-$8ffff piv tilemaps, preceded by lookup table $90000-$9ffff sprite tilemap data, preceded by lookup table $a0000-$affff sprite tilemap data, preceded by lookup table $b0000-$cffff TC0100SCN tilemaps, preceded by lookup table Note that only just over half this space is used, rest is 0xff fill. $d0000-$dffff is the pivot port data table Four separate start points are available, contained in the first 4 long words. (Data words up to $da410 then 0xff fill) $e0000-$e7ffe is a logarithmic curve table This is used to look up perceived height of an object at "distance" (offset/2). ffff 8000 5555 4000 3333 2aaa etc. (tapering to value of 4 towards the end) The sprite routine shifts this one bit right and subtracts one before poking into spriteram. Hence 4 => 1 $e7fff-$e83fe is an unknown word table $e83ff-$effff empty (0xff fill) $f0000-$f03ff unknown lookup table $f0400-$fcbff series of unknown lookup tables Seems to be a series of (zoom/rotate ??) lookup tables all $400 words long. (Total no. of tables = 25?) Each table starts at zero and tends upwards: the first reaches 0xfe7. The final one reaches 0x3ff (i.e. each successive word is 1 higher than the last). The values in the tables tend to go up smoothly but with discontinuities at regular intervals. The intervals change between tables. $fcc00-$fffff empty (0xff fill) Additional notes : 1) 'wgp' and 'wgpj' LAN stuff : LAN RAM seems to be 0x4000 bytes wide (0x380000-0x383fff in CPUB) Lan tests start at 0x00f86a (CPUB) where a copy of the 256 bytes from 0x00f8d4 is made to 0x383f00. This is text about the version of the LAN stuff ("1990 VER 1.06") . Note that at least version 1.05 is required. Dip Switches : To see the effect of the "Communication" Dip Switch you must add the memory read/write handlers for 0x380000 to 0x383fff instead of using the 'lan_status_r' one. Of course, there will be an error message, but this might help in finding the useful addresses in the LAN RAM. Note that the first time you run the game with the new handlers (I've put standard RAM, let me know if you have a better idea), you'll need to reset the game ! Is it because the tests in CPUB are too late ? In the "test mode", if "Communication" Dip Switch is ON, you'll see "NG" ("Not Good") under each machine ID (this is logical). Be aware that the "Machine ID" Dip Switch must be set to 1, or the tests are NOT performed (I can't explain why for the moment) ! 2) 'wgpjoy*' LAN stuff : It is very surprising, but you also find the text about the LAN stuff in the ROMS (still version 1.06), but you can't perform lan tests in the "test mode". As the LAN version is the same, I'll have to look at the code to see where the differences are. 3) 'wgp2' LAN stuff : I haven't tested the LAN stuff for the moment.
