Skool Daze

General information

The classic SkoolDaze game is finally available for your Atari!
In the role of our hero, Eric (or any other name you decide to call him and the rest of the cast), you know that inside the staffroom safe are kept the school reports. And, being Eric, you realise that you must at all costs remove your report before it comes to the attention of the Headmaster.

Instructions

The combination to the safe consists of four letters, each master knowing one letter and the Headmaster’s letter always coming first. To get hold of the combination, you first have to hit all the shields hanging on the school walls. Trouble is, this isn’t as easy as it looks. Some of them can be hit by jumping up. Others are more difficult. You could try and hit a shield by bouncing a pellet off a master’s head whilst he is sitting on the ground. Or, being Eric, you may decide to knock over one of the boys and, whilst he’s flattened, clamber up on him so that you can jump higher.

OK. So all the shields are upside-down, disorienting the poor masters. Knock them over now and, before they can stop themselves, they’ll reveal their letter of the code. All except for the history master, of course, who because of his great age and poor eyesight can’t be trusted to remember. His letter has been implanted into his mind hypnotically. To make him reveal it, you must find out the year he was born (which, in case you were wondering, changes each game). Then, creep into a room before he gets there and, if the board is clean, write it on the blackboard. When he goes into that room and sees his birthdate he will, as if by post-hypnotic suggestion, give away his letter.

Now that you know all the letters of the combination, all you have to do is work out which order they go in. You know that the Headmaster’s letter is always first, but as for the other three … you’ll just have to try the various possibilities. Find a clean blackboard and write out a combination.

Rush back to the staffroom and jump up to reach the safe with your hand. If nothing happens, then the combination must be wrong, so you’d better find another clean blackboard and try a different one.

With the safe open, your troubles still aren’t over, as the upside-down shields are rather a giveaway. You now have to hit all of them again.

Done it? Congratulations! You are now allowed, along with all your friends, to move on to the next class at school. But remember, there will be reports at the end of this term…..

Source Code

Game is built upon binary image of C64 version, with I/O, screen and sound routines patched with their Atari counterparts.

Code features small library to handle PMG overlays for the screens. Each PMG overlay is built from:

  • PMG data in RLE compressed form
  • table of scanlines where DLIs occur
  • table of initial values for GTIA registers (applied during vblank)
  • tokenized DLI interrupts, with code dynamically built at runtime

There is a function which applies NTSC colour fixes. I’ve also prepared a function which can erase arbitrary rectangle of PMG, which is used when speech bubbles are prepared.

Sounds and musics are ported directly from C64, with frequency values recomputed, and basic envelopeĀ  emulation.

The game attempts to run at 50Hz speed, as Spectrum original. C64 version was limited to 25Hz.

For the details about how to build the code see readme.txt in the archive.
