NanoBoard Midway Galaxian v0.91 =============================== This RBF files run the original arcade Galaxian ROM image on the Altium NanoBoard. You will need a VGA monitor and a PS/2 keyboard plugged into the "PS2 KB" connector on the NanoBoard. There are two versions of the game included - one for the (prototype) v1.3 NanoBoard, the other for the (production) v1.6 NanoBoard-NB1. Controls ======== 5 Insert Coin 1 1P Start 2 2P Start Joystick Left Joystick Right Fire S Service Switch Dipswitch Settings ================== 7..3 (Unused) 4 Lives (00=2, 01=3) 1..0 Bonus Life (00=7000, 01=10000, 10=12000, 11=20000) *SPECIAL NOTES* =============== Note that this RBF file contains the copyrighted Midway ROM images. Please use discretion when distributing this file. Starfield --------- The background starfield is currently an approximation of the real thing. It uses the same LFSR as the original, but as the screen is rotated in this version, the stars are drawn in a different order. But in theory, the number, distribution and colour of the stars should be exactly the same as the original. Scrolling of tilemaps exhibits an 'off by 1' bug which appear as glitches - most notably on the attract screen score table. The current sprite/tilemap system has an x-direction granularity of two (2) pixels. As a result, all scrolling in the x direction is by 2 pixels - this will be rectified in later (64-colour) versions. T.B.D. ------ * fix x-axis granularity * sound (WIP) Contact =======
