View source for Black Tiger CPC-Spectrum Comparison

[[Black Tiger]] is quite infamous for being one of the laziest speccy port.

And even more infamous because the speccy's original version is not even that good to begin with.

*Graphics : the Amstrad version use unmodified Graphical Datas. 

The Sprites and tiles are stored in RAM in 1bit per pixel, sprites are also masked in 1 bit per pixel. the 1bpp datas are then turned into Mode1 2bit per pixel when they are to be displayed into the Video RAM area. Which is somewhat CPU intensive.

*Also some Raster interrupt are used in order to get more than 4 colours displayed on the screen.

But the main problem is that it is quite useless as the Game's window is still monocolour ! So it simply wastes CPU power.

==What If ?==

*What we quite got :

*What we could at least have :

[[File:BlackTiger mega map speccy recolored.png|560px]]


*As the sprites are 1bpp + 1bpp mask , this means that if properly recoded in 2bpp they use the exact same amount of DATA in RAM, but could then be in 3 colours, 4th colour being used as mask, s used in super wonderboy (this is not shown on mock up)

*Also it may be possible to apply some king of "attribute colour" on the tiles so the Background and Foreground tiles, while still being 1bpp/2 colours...you may be able to set the ink (other than black) into one of the 3 other inks (from the Mode1 palette) as shown on the Map Mockup.

*Then get rid of Rasters interrupts/palette change to gain some CPU or even the few RAM needed by such routine..

There, you have a better version than the speccy one.

==Pure lazyness ?==

It is to notice that the Disk version actually use multiloads...

As it seems to reload datas between each levels...

So the Amstrad version is just some pure applied Lazyness and Scroodgery.

Such a shame for what used to be one of the best Arcade Game of 1987.
