Not quite a GTW64 entry, but an earlier build of the released Gyruss (a brilliant Konami arcade conversion) for the C64 – recovered thanks to preservationist Ken Van Mersbergen.
This prototype dated 2nd May 1984 was found within the collection of disks/materials from the archive of a retired programmer who used to work for Roklan and On-Time Software.
There doesn’t seem to be much in the way of differences that we’ve found so far apart from slightly different attack waves.
Professor Chaos got in touch via the comments to say that there are two differences to the final version and described by him as “theoretical or VERY rare glitches”. One in particular was where it goes straight to a level complete animation when all the enemies finish exploding.
In the final version, an extra check is added to make sure you are still alive (as you could still run into an enemy shot for example). Another difference was the removal of some code that when an enemy’s sprite block is blank, it’s y-position is set off-screen. Professor Chaos suggests that maybe this was unnecessary and removed to make room for the above fix in the first difference.
So, not a major difference to the final version at all – but good to see these different builds preserved, as you just never know what may surface.
A huge thank you to Ken Van Mersbergen for his fantastic preservation work and for preserving this prototype. Thank you to Professor Chaos for checking through the code and highlighting the minor differences present.
Apologies all, a bit manic at work and home this past month – so this month the update is a bit quieter than normal. Hopefully we’ll have a bit more time before the Christmas break to build up our usual large update of unreleased gems. So for this month we have:
Another month already, and not entirely sure where the time has gone! A slightly busier update this month, as we have gone through and tidied up some of the pages and removed a load of broken links, as well as adding our usual scan additions and small updates over the past 4 weeks. Hopefully in some way this will provide a highlight of some titles you may not have seen or read about yet.
Undead to be “resurrected”!
News just in, with Undead to be put into development once more after 31 years since its cancellation. Yet another title that could escape the vaults!
As the summer starts to draw to a close, we preserve an early Hungarian Tetris clone thanks to Csaba Virag. Then we take a look at what seems to be a long lost Commodore 64 conversion of a PET/VIC 20 title, two other Magic-series sets of titles that are at large, a long lost and promising game from Norway and a potential conversion of a late Mikro-Gen title. This along with 16 updates to existing entries, with a few findings and additional details added. Enjoy! Continue reading →
Platforms: Commodore 64, ZX Spectrum and Amstrad CPC
Mega Twins (known as Chiki Chiki Boys in Japan) was a sickly cute platformer produced by Capcom in the early 90’s, a slight sideways turn from the likes of Strider, Final Fight and Ghouls n Ghosts, no doubt to tap into the younger players and their 10 pence pieces. Many of us probably would have vomited at the sight of it and went back to kicking several barrels of crap out of bad guys in Final Fight.
The game consisted of you controlling two twins who carry swords and had to cross various platform levels to kill the dragon which killed their Father and find the Dragon Blue Eyes stone and save their world. The game was predominantly a sideways scrolling platformer, but with some vertical scrolling portions and a later castle level, where you would climb vertically to mix things up a bit. Large guardians would feature throughout as well to provide a fair challenge to even the most hardened of gamers. Continue reading →
