Hi
My Name is Tim Flanders and the games were published under Sumlock (I other Scramble for someone else but I can't remember who).

I have no problems with the being available on your website. WWW.timsplace.plus.com/

I would only complain if someone sold them commercially so I reserve that right.  I think it is nice to see them still available all be it under an emulator which does not do any Vic 20 games justice.

I recently bought an old Vic to show my 24 year old son what the games were like - he hadn’t seen them.  I had to remind him how much 3K was.

The games are, as far as I recall:-

Space rescue
Arcade take off game.

Multitron
I took a week off writing castle bloodstone (finished but not published) and wrote this by taking some of the graphics and code. This was technically one of my best games as it does a lot in 3k.  the best part for me was the fact that bullets (up and down) were handled by screen/memory scan and so they were not variables on their own which is why so many could be on screen at the same time.  All the different bad guys were also the same graphic number with different values pasted in. I must have been happy with it as I remember that after so many years
 
Starship Escape
16K expansion required.  Not a great game but there were some neat ideas like using Dr Who's K9 to attract bad guys whilst you got part of your 9dismantled) ship.  It was also a graphic (don’t laugh) adventure, there weren't too many of them around at the time.  A long time later there was a Toe Jam and Earl game whose mission was to find all the bits to their space ship - just like Starship Escape I suppose.

Destroyer
This is my second favourite (behind multitron).  A couple of reasons.  First it was a good working version of the classic ship versus subs game which I got for the Sharp MZ80K - it was that game that inspired me to learn machine code.  The other things about it were the addition of planes, the white noise sound before they appear and the addition of the (crude) radar.

Gunfight
The only thing I was proud of with this was it was two player - there were no two player games when I wrote this (as I knew at the time) and this allowed 1 joystick and one on keyboard)

Astro Figthers
Asteroids type two player game - the less said the better.

Space Bomber/Man on the run
Compilation because I said one wasn't worth paying for maybe two was ok

Chopper                                         
An awful game which doesn’t get better with age.  Concept was ok but implementation was very bad.

In Conclusion
There may be others but it's such a long time ago - they were written about 1981/2.  I wrote a large number/many similar games for the Sharp MZ80K, there was much more ram with this machine (Z80 processor too) so they should have been better.  These too were marketed under SUMLOCK.

The reason I wrote the games was because I bought a Sharp MZ80K and got some games with it.  The games were very bad bar the destroyer type game which was machine coded.  As there were no courses available for me at the time I wrote games as a way of teaching myself programming.  The plan was to learn well enough to get a job and support my family, strangely the money came in from the games only after I found employment.  If I had received income earlier who knows how my life would have turned out because I loved writing games, especially when my skills had improved.  Anyway I got a job programming pharmacy systems and, due to some strange events, I ended up owning my own company and I retired about 6 years ago with enough money to live comfortably. 

I still wonder how things might have gone had I carried on with the games and, even though I am 45 now I still but lots of games and play them.  I like 9not (exclusively) strategy games from Starcraft, C&C through to a nice middle earth one EA did recently.
Although crude I had plans for similar game for the Vic 20 though it's ambitions were limited to two teams of self aware characters battling it out on a single screen, still the idea was there that's something.
Even now I feel that games developers seems to think that old thing called playability is of secondary importance and yet it is the first thing to get right.
