Re: What game would you like converted to the Next?

Sinclair was depending on a brand new technology to make its ULAs (programmable logic) which allowed the cost reductions necessary to make an inexpensive computer. The capacity of these early devices would limit how much integration you could achieve. Other competitors like Commodore and Atari made...

Re: What game would you like converted to the Next?

a new spectrum would have had to attack colour clash and limited colours. Those limitations were a function of 1982 costs and technology and would not reflect anything new or competitive made in 1990+. Cost - yes, technology - no. Dozens of colors in home computer is late 70s, hw sprites is late 70...

Re: What game would you like converted to the Next?

This is what games look like when you eliminate the colour clash. That is the quintessential difference between the 16-bit era and the 8-bit era. But for some people the important question is how it is being achieved It is up to the programmer to take it in the direction he wants to, whether that b...

Re: ZX ULAX emulator

Batty looks great! Just enough colour to lift the sprites/score off of the background. TBH i felt a bit lazy (again) and just assigned same colors for almost everything :) while metallic bluish seemed right for the most objects, maybe bonuses might look better different so if someone feels like add...

game pack update

Never was a big fan of Batty - found it too hard, too fast and too unfair with bonuses for my liking (the best of all ZX Breakout clones is Impact IMO). But some people think Batty is a great game and requested it repeatedly. So here it is, looking even better than ever (the one undeniable thing abo...

Re: Colour Attribute Address

I believe you already know how to obtain a bitmap address from your X and Y coordinates. The attribute address is derived from that. Assuming HL holds the bitmap address: ld a,h ;calculate the high byte for the attributes rra ;(the low byte is the same) rra rra and 3 or 88 ld h,a ;back into H. HL h...

double update

public beta 19 fixes and improves some things overlooked in the earlier versions. The most important change is dux loader now using the active address mapper to place some recolored pixel data into the "screen memory" area (instead of sending everything straight to the "pixel memory" as before). It...

Re: Atari 8Bit Colour Pallette

No, it IS about the machine limitations as well. In short, Atari 8bit has excellent "vertical", but very limited "horizontal" color capabilities. In detail, the Atari has background and sprites. There are no set screen modes for the entire background, as it is actually a customized stack of separate...
