Gemintronic

Not me. Tried Pale Moon, Firefox and Chrome. Just downloaded the 5200 dev kit from that link in Chrome as well (Google loves to false flag downloads in Chrome). A Googly search revealed hits that indicate it's a Norton / Internet Guard thing.

That link I gave for Shooting Gallery could get you ramped up quickly. Sebastian Mihai not only provides the source to his games but the best version of the dev suite he used. Including documentation for the 5200 hardware and 5200bas. From what I understand 5200bas is just enough high level language to complement assembly programming.

I think a random $5 charge would confuse me. I already have to watch out for FreedomPop trying to charge me for their "Free" phone service which I stopped using years ago. I've never been disappointed with the 2 year option. Less to think about.

Didn't find a list per se but PDROMs.de lists some homebrew. Not sure if these are duplicates.

Drat. I've got a trademark on Gemintronic so I was looking for any of my games. No dice. Guess I have to make more games and give them pirate enticing names like Yaaaarrrrrrr's Yarvenge.

The PCem forum says: "I'm done. This isn't fun anymore." I heard there was drama in the past. Probably had some more going on. I think that's the worst reason of all to quit a project. The trolls win and users lose. UPDATE: Maybe not drama. Found this Reddit thread. Maybe it's just project fatigue. https://www.reddit.com/r/emulation/comments/nwk9ag/pcem_ibm_pc_emulator_needs_developers/

I think our community has amplified both the good and bad Best experiences to the point that an article like this is hard to take objectively.

I've used RevEngs paddlemini mini kernel to add an "extra" multi-colored sprite below the playfield. It was really meant to make paddle controller based games easier. But, I just used it for the extra sprite. It's limited in that you can't move the extra sprite onto the playfield proper. It can only move horizontally just below the playfield. Also, you must edit the mini kernel directly to put in your custom sprite.

Single Screen Action Puzzle.. I guess. Same as Solomon's Key, Nuts & Milk, Binary Land, Door Door, etc..

I was experimenting with embedding the ball and missiles into the player sprite for collision. My code is too buggy to show. But, maybe with your savvy at least the concept would pan out In this demo it is possible to get trapped when the player gets stuck inside the playfield. Platforms with thin floors will cause the player to fall through if they just jumped. badaegondemo.bin

I think batari BASIC users all go through the phase where we don't understand how bad the keyboard is (as a joystick). Get a cheap USB joystick and test your game with that. I use a spare Xbox One joystick.

One thing to note is that the flickering of virtual sprites can annoy the eyes of your game players. Really depends on the person and the TV/monitor being used. What I try to do is design my game so that virtual sprites never have to be on the same horizontal band as eachother.

Strangely this might be more suitable for the Atari 5200 or 7800. The mock up has multiple sprites that would be keen to seek the player. When more than two sprites are on the same horizontal plane they'll flicker like crazy.

The original poster way back in 2014 stated $70 titles being a breaking point. Also, availability. The opposite of expensive, well packaged games is experimental, simpler games with cheaper/loose cart packaging. Is there a demand for such games? It feels like the bar is set pretty high.
