bad graphics in vic 20 games from compute and compute's gazette

[bradhig1]

Two games from Compute and Compute's Gazette have bad graphics problems. Bowling Champ someone didn't fix the graphics around the scores. How could they miss that. Canyon Runner the listing doesn't match the one in the magazine the line numbers are wrong. These are from the vic 20 gamebase. Are the disk versions available anywhere?

Bowling Champ: There is one missing space on line 132, right before the cursor down (reverse Q) symbol. The original listing is ambiguous in that matter, as it could be anything from 0 to 4 spaces at that position.

 

Edit: What's worse is that the program only displays the number of points you received in your last frame, instead of the total. That might be a type-in bug once upon a time, which you would like to go through to determine the problem.

 

Canyon Runner: I'm not sure what you think is the problem, besides the fact that the game originally was published as two parts but later someone has concatenated them into a single file, which affects line numbers.

 

Both games can be downloaded from Zimmers FTP, but those versions match the ones you already got in the Gamebase.

In case you want to go through the listings, both have been scanned and partially OCR:ed which means that you could copy/paste, correct typos and run through a tokenizer like petcat to generate fresh PRG files.

Typed in canyon runner tonight. Didn't change anything. At one point the game becomes uniwinable because of a lot of obstacles in the path you can't get past.

bowling champ line 1210 had be mistyped and I fixed it.

It sounds like Canyon Runner is due for a bug fix then, 33.5 years after it was published.

If people want to supply fixed versions, I will update GB20 with them!

Ah, Canyon Runner. My first program I typed in on my new C64.

 

Edit: Oh wait... that was Canyon Cruiser. Potatoe, Potato.
