Re: Horace games

Spiders. The first two "levels" are kind of pointless, but the Space Panic bit was great and it made it the one I'd go back to again and again. Skiing had a reasonable Frogger clone, but the actual skiing bit was less fun. The original is just a bit meh.

Re: The best classic Speccy game beginning with S: vote

Difficult choice, a few really good titles. I'm going for Slightly Magic because I played it multiple times even after beating it and never got bored. I can even forgive the one really dodgy rhyme in it. It won't win, but heh ho.

Re: Was Hannah Smith real?

Hmm, she was probably real, but the ONE TRUE girlie tipster was undoubtedly the very real Linda B. I have no idea how to vote. :lol:

Re: unsigned to ascii

As above, if it's a simple score counting down, just store it in consecutive bytes as ascii chars (48-57 decimal). To decrement the score just decrement the bottom char and if it goes to 47 ('/' char), set it back to 57 then go to the next char and decrement that. That way the score is always in th...

Re: unsigned to ascii

One common solution is to use BCD to store the number, as it's a lot quicker to convert a BCD number into ASCII because you don't have to deal with any divides (just shifts) and the Z80 can do BCD arithmetic almost as fast as native numbers.

Re: "Step out" in a debugger

Either way can be defeated by weird enough code, but if I were implementing it I'd go for "step out" being equivalent to "run until a RET occurs" - it's probably what most developers would expect to happen and I suspect will give the right behaviour 99% of the time.

Re: Help with Manic Miner

The spider webs kill you - each room in MM can have two types of deadly block - such as the stalactites and poisonous pansies in Central Cavern and in AOTMT they are the web and spiders. I don't believe you can get back on the ladder. If you jump right, you'll go through it and land on the conveyor....

Re: The best classic Speccy game beginning with R: vote

So many great games it's hard to choose. I was convinced I was going for Rainbow Islands, wobbled a bit once I got to Robocop and then completely changed tact when I got to R-Type. Because nothing is better than R-Type, just a stunningly brilliant arcade conversion of a fantastic shooter. So many gr...

Re: 16K software, run faster with Russian clones?

It might be more noticeable in the Freescape titles (although they obviously aren't 16K) because they run at full speed but are slowed down enough that any speed increase might help somewhat.

Yup, this one's Quazatron, barely worth a poll.
