I’d love to see it tested on the 512 if you can! I’ve tested it in emulation with a ROM from a 512k but would love to see if there are any issues with the real hardware. I’d also like to see if it runs okay on the newer PPCs in Classic environment. Thanks! I’m running the kickstarter to...

Since there were some questions about this, here's a peek at the level editor that will be included with the final game: Levels can be up to 48 x 48 tiles, and can have up to 50 entities (enemy robots or tiles that can change without the player touching them). I'm planning to make the...

I have nothing of value to add, other than I feel your pain. I was excited to retrobrite my LC580, then was defeated when all the clips basically turned to crumbs taking it apart. My solution has just been to put it back together as best I can and just never take it apart again. Enough clips...

A lot of the mechanics are what you’re used to in chips challenge, but now that I’m turning to focus more on level design, I’ll likely be adding more traps or changing the way some work to better suit how I want the gameplay to work. The game was actually developed as black and white first...

I actually do have a tile-based level editor for it! I used it to create all the levels in the demo, and intend to include it with the finished game. It’s relatively unpolished and undocumented right now, however. During development of the game engine, I was constantly changing behaviour of...

I can see the comparison, though I think my game is more of a puzzle game, whereas PETSCII Robots is more action/strategy. The name Angry Robots actually comes from my little nephew who used to run around the house pretending to be an angry robot, so the similarity in names is a coincidence...

Over the past two years, I've been tinkering away on a new game for my Macintosh Plus. I'd like to share a working demo of the game and welcome any feedback anyone has about the game. I'd also love to hear reports of how it works on real hardware. I've done my testing on my Mac Plus, my Mac...

I found this book to be quite helpful when I was learning about GWorlds and offscreen graphics: https://vintageapple.org/macprogramming/pdf/Sex_Lies_and_Video_Games_How_to_Write_a_Macintosh_Arcade_Game_1996.pdf

If your modern software that you write for vintage computers isn't selling because there is an old free alternative available, then why did you write your modern software? If there is already some old abandonware available that serves the purpose, it seems like a wasted effort to recreate that...

Curious if this broke for you recently? I'm using an AFP share on my Synology for backup on my older macs, and just connect through TCP/IP. Never occurred to me to try that until I read this post. It worked flawlessly until the last update, and now I get this when I try to log in: Seems there...

Is there any reason why new M0110 keyboards cannot be made? With the dwindling supply of original keyboards, it seems like this may be needed. I don't have one of these keyboards (thus my curiosity), but from photos I see online, it seems like it should be fairly simple to create a PCB that...

How were software disks mass produced at the time? Surely you didn’t have someone sitting in a warehouse swapping out floppy disks on a Macintosh once a minute running DiskCopy. Are there machines that can just blindly copy whatever is on the media without a care for the format?

Thank you all for confirming my declining memory! I guess by 1998 no one was really using 800k disks anymore. I suspect I was remembering the Imation SuperDisk drives, which have a similar enough sounding name to fool me, and a quick google image search confirms that those were most likely the...

So when the iMacs first came out, we had USB floppy drives for them, since the iMacs didn't have an internal floppy drive. I swear I remember these being official Apple SuperDrives capable of reading 800k floppies. But I can find no trace online that Apple ever made a USB floppy drive, let alone...

I don't know what I'd do without you. Pallets.h! Of course! I really don't know how I made it this far without realizing the value of THINK Reference. The THINK disk I have had a demo of THINK Reference, but it was obviously quite limited and not useful. I was so focused on reading books that I...

Agreed, but the purple is just so striking! It's a shame this card will never be visible once installed...

So update, I got colour offscreens working using... GWorlds! I messed about with my code a bit more and just couldn't get it to work properly. Even setting the high bit of rowBytes didn't seem to get the desired results. So I gave up and implemented it using GWorlds, and wow, they really are...

Wow, that card is a thing of beauty. Does the card use all of the shelf parts, or does it use custom chips that need to be pillaged from an existing video card? Is this something that can be made from scratch?

Thanks Crutch! Macintosh Programming Secrets has the most detailed explanation of colour offscreens that I've seen yet, so I'll read through it more thoroughly tonight! Sometimes I scroll through the list of 158 mac programming books that are scanned on Vintageapple.org and pick one that sounds...

So, it’s been a few months since I posted an update, but things have been progressing steadily along. I’ve turned my attention to level design for the last few months, and haven’t done much with the code. The core of the game was working nicely and most of the features related to gameplay are...
