sirlynxalot Posted May 12, 2022 Share Posted May 12, 2022 Ooh this looks cool, I don't usually go in the programming forum so didn't notice a new emulator was being worked on. The possibility to do comlynx emulation sounds amazing. The lynx had a ton of multiplayer comlynx games and it'd be great to be able to more casually explore the lynx multiplayer experience without needing to buy multiple copies of same game or have multiple flash carts, or even working lynxes since they've become quite expensive in recent years.

Songbird Posted April 24, 2023 Share Posted April 24, 2023 (edited) EDIT: it is quite possible the version I used is out of date. Apologies if these issues are already fixed! I just tried Felix for the first time using the 0.5.0(156) build. It's very cool to see a new emulator on the scene, even if I am a year late! I did notice a couple of issues with it. Audio is messed up (distorted) in two different games I tried, and in Microvaders, the palette is not displayed properly. I don't modify the palette via interrupt, but I do modify the SCB palette indices each time through the game loop so I can get different color combinations on-screen for the same sprites. As an example, the below screens are oversaturated in purple. Plus the extra life ships in the lower left are somehow two different color schemes (even though I never modify this sprite). Some background stars are also green, which never happens in the game.

It's very cool to see a new emulator on the scene, even if I am a year late! Thank you for trying Felix! Version 0.5.0(156) is the latest i've published. The issue with distorted audio is a known problem. But it's not a matter of fixing anything but it's about rewriting audio/video synchronization code from scratch. It'll be the first thing I'll do when I'll resume development. The issue with SCB pallette seems to be something new. Can you prepare some simple example demonstrating the problem?

Songbird Posted April 24, 2023 Share Posted April 24, 2023 (edited) The first few credits screens display properly. It seems to only happen when I start the game. As part of the "warp in" effect, I start with the 160x102 background stretched extra wide, then gradually shrink it until it reaches the 160x102 size. At the same time, I am fading in one palette byte at a time. The global palette ($fda0) starts as all zeroes, then I execute this routine once per game loop for 32 times (palette_index increments from 0 to 31 once per game loop): FadeInNextPaletteByte ; Fade in next palette byte lda #<originalPalette sta ptr1 lda #>originalPalette sta ptr1+1 lda palette_index tay lda (ptr1),y sta $fda0,y rts If I start and end the game on the same screen repeatedly, I get cumulative palette corruption which is quite fun to see. The SCB which renders the full-screen background is only used for that purpose, so I never even change the sprite pointer or palette indices in this SCB. Indices are used but simply set to 01 23 45 67 89 ab cd ef. First two bytes of SCB are set to c0 30. Since the enemy invaders and score text are also corrupted, and they use separate SCBs, I am guessing the global palette is not updating properly.

laoo Posted December 19, 2023 Author Share Posted December 19, 2023 (edited) I wasn't taking part in LynxJam 2023 but surprisingly it was fruitful in the field of emulation. Two of the entries wasn't working correctly in Felix and it bugged me and @42bs enough to investigate why. It turned out that there was two separate bugs. One-liners actually. But fixing them was so joyful, that I decided to make it into another Felix release... after... two years and ten days So here it is: Felix 0.6.0 With too many changes to mention them all. I encourage to check it out and stop using all those unofficial builds that surfaced through these two years. Not sure when 0.7 will came out (I hope earlier than in next two years) but I'm planing to do migration to multiplatform rendering engine till then so Felix should be finally able to run natively on non-Windows platforms Edited December 19, 2023 by laoo 6 1 Quote Link to comment https://forums.atariage.com/topic/326441-new-emulator-felix-help-needed/page/6/#findComment-5369961 Share on other sites More sharing options...

Of course i wanted to try it out immediately, but sadly i have a 32bit system (Win7) and if i try to start it, i only get the message, that i can not run it on my machine. Therefore i wanted to ask, if you could release a 32bit compatible version of "Felix" too? It would be really great, to have another Lynx emulator, because updates for "Handy" are also very rare and some newer released Lynx-demos, no longer work on it. One of my friends told me, that they work on "Felix". 😀 Quote Link to comment https://forums.atariage.com/topic/326441-new-emulator-felix-help-needed/page/6/#findComment-5371728 Share on other sites More sharing options...

It wasn't easy, but I managed to configure the solution to produce 32-bit executable. I haven't tested it too much, so I'm not sure whether it'll run in all circumstances. I don't know what CPU do you have, but Felix is quite CPU-hungry, so it might not run well on older machines. Nevertheless, I'm attaching the 32-bit executable here. I don't want to add it to a release now as I'm not sure about the stability of this build.

First of all - thanks for the efforts, regarding the 32bit version. I also get a virus-warning from my system and then I ran the file through "VirusTotal" online and this was, what was shown to me: Of course, as "Nop90" already wrote, this can also be false positives, but that's why I haven't dared, to try out this 32bit version yet. Maybe it's the compiler, that's no longer completely up to date? This could also be an explanation. What do you think "laoo", are these definitely false positives? I just want to be sure, before I start this new 32bit-version. And I wish everyone here a Merry Christmas! A reply after the christmas feast days, is completely sufficient.

Songbird Posted December 29, 2023 Share Posted December 29, 2023 I tried Microvaders on Felix, and am observing a few issues: Sometimes the screen stays black even though I hear sound. This has happened both on the very first boot screen, but also later when displaying an in-game story screen. Sound is not accurate. Music is playing faster and sounds corrupt / distorted compared to Handy or real Lynx. Is there a way to rotate the screen for vertical play? There is an issue with reloading the palette. If I say "yes" to play again after losing a game, I get random colors in the palette. It continues to change each time I play again (all within the same cartridge boot). All of the above are observable on the public beta I released last year. You can also see screenshots of how the game should look. https://songbird-productions.com/2022/12/16/microvaders-beta-now-available/ Here are some corrupt screens. Let me know if you need any more details. 1 Quote Link to comment https://forums.atariage.com/topic/326441-new-emulator-felix-help-needed/page/6/#findComment-5376333 Share on other sites More sharing options...
