Please set a floppy disk properly and press the return key. Retrying.") - Super Billiards (X1 Pack 14): has a slight PCG timing bug, that happens randomly; - Trivia-Q: dunno what to do on the selection screen, missing inputs? - Turbo Alpha: has z80dma / fdc bugs, doesn't show the presentation properly and then hangs; - Will 2: doesn't load, fdc issue presumably (note: it's a x1turbo game ONLY); - X1F Demo ("New X1 Demo"): needs partial updates, but they doesn't cope well with current video system; - Ys 2: crashes after the disclaimer screen; - Ys 3: missing user disk, to hack it (and play with x1turboz features): bp 81ca,pc += 2 - Ys 3: never uploads a valid 4096 palette, probably related to the fact that we don't have an user disk Notes: - An interesting feature of the Sharp X-1 is the extended i/o bank. When the ppi port c bit 5 does a 1->0 transition, any write to the i/o space accesses 2 or 3 banks gradients of the bitmap RAM with a single write (generally used for layer clearances and bitmap-style sprites). Any i/o read disables this extended bitmap ram. - I/O port $700 bit 7 of X1 Turbo is a sound (dip-)switch / jumper setting. I don't know yet what is for, but King's Knight needs it to be active otherwise it refuses to boot. - ROM format is: 0x00 ROM id (must be 0x01) 0x01 - 0x0e ROM header 0xff16 - 0xff17 start-up vector In theory, you can convert your tape / floppy games into ROM format easily, provided that you know what's the pinout of the cartridge slot and it doesn't exceed 64k (0x10000) of size. - Gruppe: shows a random bitmap graphic then returns "program load error" ... it wants that the floppy has write protection enabled (!) (btanb) - Maidum: you need to load BOTH disk with write protection disabled, otherwise it refuses to run. (btanb) - Marvelous: needs write protection disabled (btanb) - Chack'n Pop: to load this game, do a files command on the "Jodan Dos" prompt then move the cursor up at the "Chack'n Pop" file. Substitute bin with load and press enter. Finally, do a run once that it loaded correctly. - Faeries Residence: to load this game, put a basic v2.0 in drive 0, then execute a NEWON command. Load game disks into drive 0 and 1 then type run"START" (case sensitive) - POPLEMON: same as above, but you need to type run"POP" ================================================================================================= X1 (CZ-800C) - November, 1982 * CPU: z80A @ 4MHz, 80C49 x 2 (one for key scan, the other for TV & Cas Ctrl) * ROM: IPL (4KB) + chargen (2KB) * RAM: Main memory (64KB) + VRAM (4KB) + RAM for PCG (6KB) + GRAM (48KB, Option) * Text Mode: 80x25 or 40x25 * Graphic Mode: 640x200 or 320x200, 8 colors * Sound: PSG 8 octave * I/O Ports: Centronic ports, 2 Joystick ports, Cassette port (2700 baud) X1C (CZ-801C) - October, 1983 * same but only 48KB GRAM X1D (CZ-802C) - October, 1983 * same as X1C but with a 3" floppy drive (notice: 3" not 3" 1/2!!)
