A7800Hawk issues (upd. 2020-06-27)

LAST EDITED (June 27 2020 1:37 PM) -- 4f7c1a0

Here are the remaining game with minor or huge glitches for the Atari 7800 (prototypes excluded)

The Original 59 games

• Basketbrawl
• Summer Games :

In both case, the game are playable without problems, save for the graphical glitches.

Homebrews

• Serpentine : Game crashes right at the beginning. Author say that it require extra RAM and has a POKEY mode if enabled

Other game that were previously fixed

• Choplifter
• Realsports Baseball
• Tower Toppler
• Pac-Man Collection (No Sound, but game works) (POKEY)
• Super Circus Atari (No Sound, but game works) (POKEY)
• Bentley Bear's Crystal Quest (Sounds work , but now the player graphics are broken) (POKEY)
• Astro Fighter (Game is not controllable and seems to play "by itself", like Tower Toppler)
• Crazy Brix (Game is not controllable and seems to play "by itself", like Tower Toppler)

1. You'll need to bind analog controls to something in COnfig -> controllers -> analog controls.
2. This is currently fixed in master, please test.
3. Pretty sure Choplifter is supposed to look like that (that part is off screen on most TVs.) The others need looking into.

Thanks you for the quick answer, I just noticed that a very recent version of Bizhawk was out last week, ill make quick test right now and ill report in a few minutes

I should have checked about the current version before writing this issues, I am sorry about that

The Light Gun Games now work, I tried all of them and they all play correctly.

Realsports Baseball doesn't have the scrambled Scoreboard anymore, it display correctly

Choplifter and Basketbrawl still have their graphical glitches, but they are really minor to the point that ive did some editing in the gameplay clip to put solid colors over the glitches

Commando seems to have the same problem thought. The POKEY Music volume is very low, and ive checked some video about it on Youtube, such as this one : https://www.youtube.com/watch?v=-DjnGy_ZKLs which play the music at a higher volume.

The POKEY fix didn't make it into the release build.

Please try the dev build: https://ci.appveyor.com/project/zeromus/bizhawk-udexo/build/artifacts

I'm still pretty sure that choplifter is correct, but Basketbrawl will definitely need to be fixed.

Commando do seems to work well with the dev version, the pokey sound is high enough

I noticed however, that Summer Games has some text glitch for the events in both the dev and current version of Bizhawk. Winter Games doesn't have those problems, despite being based on the same engine. The games is playable without crash thought.

EDIT : I don't know if it is a normal game behavior or not (the manual say nothing) but as soon as you start a game in Tower Toppler, at the moment the level start, it is skipped like it was completed and cycle through all the level, not being able to do anything. I tested 2 different roms. I have used the NTSC Filter feature from the emulator. It happen both on current version and dev.

Beside that, I managed to record every games but Summer Games and Tower Toppler, Homebrew and prototypes are excluded for now.

I did a tour of the 25 Atari 7800 games offered by Atariage and most of them work well, with the exception of 5 games

Pac-Man Collection (No Sound, but game works) (POKEY)
Super Circus Atari (No Sound, but game works) (POKEY)
Bentley Bear's Crystal Quest (No Sound, but game works) (POKEY)
Astro Fighter (Game is not controllable and seems to play "by itself", like Tower Toppler)
Crazy Brix (Game is not controllable and seems to play "by itself", like Tower Toppler)

for the games that play by themselves, try switching the difficulty switches. Tower Toppler cycles through the levels with default difficulty switch settings. It's a deliberate feature of the game.

For pokey games, you'll need to add them to the gamedb with pokey=true

I tried the above solution, it work for Crazy Brix and Tower Toppler (both seems to use that feature for level select). However, either Astro Fighter is a bad dump I have or it is just not working correctly. In the cases of the Pokey Games, I have enabled it in the gamedb and reset the emulator, but it doesn't seems to do anything (Do I need to do other things before reseting the emu?)

[alyosha-tas]

ok, so looks like the pokey games are using a mapper that I didn't give pokey support to yet. I'll try to look into it.

@Glitcholog : I added pokey support to the required mapper. All I could find to test on was a demo version of Bentley Bear, but it seemed to be working alright there. Please test and let me know how it works.

Also if you have hashes for the games I can add them to the DB once it's verified working.

I tested on the lastest build (October 24) and it doesn't seem to work at all on the three roms (still no sound). Also, since ive never did that, how can I create a hashes for the roms?
