I found this on another forum and thought people might be interested: http://bizzley.com/ Its a free e-book and info about the development of the ZX Spectrum version of R-Type. Fascinating reading if you want to understand just what went into making a game back then
Thanks for the link. R-Type on the Spectrum is one of the greatest conversions ever - to someone unfamiliar with the Spectrum it won't look like much, but you have to remember that the Spectrum has no hardware-sprites, no hardware scrolling, only fifteen colours, only allows two colours per 8x8 pixel square, and (in the 48K model, which is what this game was written for) the Spectrum actually stops dead whilst playing a sound*. Even so, the Spectrum had many of the best 8-bit games ever made, which shows what can be accomplished by talent and hard work, and makes you wonder what a PC could do if instead of having new hardware every couple of years, programmers stuck to one base model but really pushed it... Anyway, compare R-Type on the Spectrum to any other Spectrum shooter and you'll see how amazing the R-type port is. * Actually, by quickly stop/starting a sound, you can create the illusion of non-stop sound whilst the games are playing, as any decent game on the Spectrum does, but this does east into the CPU runtime. Clever programming overcame most other limitations, but as always, you ended up having to compromise on what you wanted versus the cost in memory and/or runtime. For example, a common trick in vector graphics games on the 8 bits was to create a look up table of values instead of having the 3D co-ordinates computed in real game time, as using a look up table was much faster than the 8 bit's relatively simple 8-bit, integer only, CPU. But of course this meant spending part of the very limited memory on the look up table, memory which could have been perhaps better spent elsewhere. In some respects, modern programmers have it so easy!
Thanks for the heads up. It was indeed a great conversion and no doubt this will be an excellent read!
This was a really great read, I never had a spectrum but R-Type on the PCE was a big deal for me at the time. This part in particular was interesting news to me too.. " There is some confusion as to just what happens when you get to the end of Level Six since it doesn't have an End of Level Boss like the other levels, it just sits there pumping out Pistons for a while but some people insist that when they got this far there was indeed an End Boss. This all stems from the PC Engine\TurboGrafx-16 version where after blasting away a number of these Pistons the screen starts scrolling again and introduces a large alien that hugs the ceiling and occasionally splits in half shooting off fireballs. I suppose somebody somewhere decided that the original arcade ending wasn't exciting enough or lacked symmetry with the rest of the game but it's not there in the original so we didn't put it into our versions." I never got that far in the game when playing the game in an arcade so I never realised that boss was unique to the pce conversion. *oops, sorry for the double post. I should have just edited the original.
When I think of R-Type on the Zx Spectrum, or C=64 for that matter...) I'm always reminded of the shameless cash-in by Rainbow Arts that, I think, got shelved because it was just too similar... or possibly better? Does any remember the name of the game? ...and thanks for the link, that's an interesting read!
Forgot to say, thanks for posting this up. I love reading about development stories from the Spectrum era. If you've not seen it before it's worth watching commercial breaks on youtube which details the rise and fall of Imagine software - it also features Ocean software as well. About half way through the program the company (imagine) goes tits up due to overspending and they end up getting kicked out of their office by bailiffs!
Since this got bumped anyway wanted send out a big thanks to the person who posted it. That's a great story, written well.
True, I read it a while ago and it was a fantastic paper. Good to have the story documented and preserved. Highly highly recommended. pd. The imagine fall docummentary was also really good. I do love those insider stories
