Surprise update to Oid. Speeds ups for the most part.

Very fun and super background graphics! Good job all around!

Sorry it took so long to reply Tangentg. Get the latest version from the first post of this thread. It is the last one (bottom) of the list. There are so so many ways to run a Atari emulator I'm not sure the one you had the problem with.

Ah OK. Not sure then. Left Switch on B = Easy game Left Switch on A = Harder Game SWITCH A: Gravity is more of a factor Ball behavior is different Joystick up for both flippers is disabled. Wall hits are slightly different. The tilt is more sensitive. If the left difficulty is set to A, the joystick up which fires both flippers is disabled. If set to B, joystick left = left flipper, joystick right = right flipper and joystick up fires both flippers. B is the easier choice. All I can think of.

Glad you like it. Make sure you have the latest version... alien-pinball-08.bin.

Thanks for the update! castration-free license on Salvo music... BTW, seeing the Salvo game made me want to look at 7800 development. Great job.

Thanks! I like Notepad++ so far. I've started defining my own AT7800 language in it, which is nice. I had hoped for this feature.

Got GIMP setup today (I think) and just successfully compiled a sample program. Getting ready to start reading about the commands. What is recommended for an editor? JEDIT or just use notepad (Windows 7 btw). Thanks for the development of this RevEng!!

Super nice! I just saw this. This could be the greatest hack of all, but them I've always been a huge WOW fan.

Wow. Nicely done!

Only issue I've seen under Windows 10 is that it does not save it's options, so each time you run it you have to re-set it up. Other than that I have not had any issues under Windows 10.

Thanks Papa! As for the cart question, I have never followed up on the process to do that, so I'm not sure. I guess it would be nice to have a cart of it though if enough people wanted one. I don't have any idea on how to measure that either.

Doom Patrol 0.7 released. This is optimized and harmony cart ready. Some minor updates also. Special thanks to iesposta for helping to optimize this one! He showed me some great stuff! This ends my getting into scan line compliance and just in time as the new Stella has been released. Now, I can finally get on with making some new stuff

Whoops, I mean Doom Patrol..

Wahoo... and I just finished (I think) removing all the jitters from The Deep.

Thanks for trying it out! I can't explain why it could be different on a 4 switch and a 7800. Someone with deep knowledge of the hardware might chime in?

Thanks Iesposta! I'm a bit fond of ORB also. The games are different because I'm trying to learn new stuff. Very nice scrolling effect! A bit hypnotic. I happen to be working on a scroller game currently, but don't expect something as cool as your demo Would be awesome to see your code and tricks on this one.

Are you sure that's just not the standard flicker when two sprites are close by? I tested this a ton using the Stella debug command breakif { _scan > $262 } and the break was only triggered when the player hit Select or Reset.

Orb release 0.9 (see first topic post). A ton of code shuffling in this one. The game no longer exceeds scan lines unless you do a Select/Reset on it. I felt this is acceptable. Some graphic changes, some enemy logic changes, additional animation. The ground WILL now harm your ship so try and avoid it. As always, let me know if you see problems.

Yes, I've noticed those commands are hogs. Don't understand why they consume so much space. They are not used in this game. Also after reviewing RevEng cycle post above. I'm getting killed on banked gosubs, which I changed wherever I could in this game.

A youtube lets play of Alien Pinball:

The Deep 0.4 release (see initial topic post). Whew... I have tested, moved, squeezed, danced (no I didn't dance), but this one does not exceed 262 scan lines. I did get to memorize the breakif command, and play the game no telling how many times. I also got to learn a couple of things and found a bug. Is there a list of what statements cost in terms of cycles? If you have a harmony, give it a spin. There should be zero jitter.

Nope I haven't tried that. I've been trying to eliminate cycles instead, but will give it a shot. Thanks!

A lets play video of Cows by Killa. This was my first attempt at trying to write a 2600 game. Killa will be looking for more 2600 homebrews to do lets plays on so drop a comment on him of homebrew games you would like to see.

Thanks for trying it and the feedback SpiceWare. On the screen transitions I've tried lots of stuff, none make much of a difference. My hope is the jitter there is just not very distracting. The 4 enemy issue I have optimized a bunch, but apparently not quite enough. I pulled out some sprite animation also. My other choice would be to pull out a bad guy which I really hate to do. Guess I'm going to have to purchase a Harmony cart at some point or wait until your code changes are in Stella. On the plus side, it plays wonderful on a Nvidia Shield TV
