Whichever gives the better result. The frame counts and FPS will be the same if used in Daphne, but obviously the resolution will be SD, as the original Daphne couldn't support those title in HD. We have tq, and ace and lair, lair2 in higher resolution, as they were supported in original opengl, albeit not 4k. As you said, some experimenting..... Don't feel you have to go to 2880x2160, 1440x1080 would also be a huge improvement.

I would suggest, 'esh' or 'sdq' might be good to play with ? Others that we don't have are: bega, cliff (for Daphne), galaxy, gpworld, interstellar, mach3 or uvt

Thanks @Nit3H8wk for info. Basically, you need to maintain the same Frames per Seconds (FPS) and aspect ratio as the original video. In Windows: https://mediaarea.net/en/MediaInfo/Download/Windows this tool might be useful. View -> Tree Debug -> Advanced Mode Look for 'Duration', 'Frame Rate' and 'Frame Count' Look to keep these as close to the original as possible. Beyond that, you need to look for filters that clean up the video, (only a few) have tried this before, so try and see what looks good..... ffmpeg: https://ffmpeg.org/download.html The final conversion from MP4 to M2v would use something like this: ffmpeg.exe -i <original>.mp4 -an -b:v 21400k -codec:v mpeg2video <game>.m2v Maybe force FPS with: ffmpeg.exe -i <original>.mp4 -filter:v fps=29.970 -an -b:v 21400k -codec:v mpeg2video <game>.m2v Alter bitrate (-b:v) as appropriate.

I haven't performed this myself, but from @Nit3H8wk I believe https://topazlabs.com/ is the software used. I also think that decent GeForce RTX can be used to offset the CPU usage in the latest versions. I'm sure slower capacity systems will also work fine, but just take longer to process the video.

Disclaimer, any advise given should be taken as purely that: Advise. Please do your own research Any on them would do what you want. I'm not sure what the marketplace is like where you are, but eBay might give you a better price on these refurbished deals. Especially for the GT 710. It depends where you want to put the PC, this will dictate what form factor of the case, is better for you. For Retrogaming you are emulating very old hardware, so don't need much CPU. But if you start adding 4k video into the loop, then you have to have the means to deal with processing and displaying it. Hence the GT 710. But any i5 (or i7) processor of 3rd gen or newer will blow the RPi out of the water. Edit: I would look for one without a hard drive and Windows, then put a decent SSD and install Ubuntu, save yourself a few bucks.

List of games: All the Daphne games + all Singe 1 games + games ported here: https://github.com/DirtBagXon/hypseus_singe_data The RPi is still very under powered compared to a full spec PC, running Windows or Linux. In fact the Pi4 has lost some power in dealing with MPEG-2 video: You will have far more success with 4k content on a cheap PC, and stick a second hand GeForce GT 710, or similar, in there. Then run Ubuntu on it if you are feeling adventurous - (you can then install RetroPie on top). Or go the Windows route. I like the RPi, but people expect too much of it. Another choice is to get an 'old' MSI Cubi or Intel NUC, if you can find one at a decent price. But your 4k experience will depend on model. My 2c.

I have no idea if SDL will handle the conversion down from 4k to that resolution on a CRT, and have no means to test. But it does seem a waste of CPU cycles dealing with that video resolution, on a display which would show SD content comfortably. If that doesn't work, just grab the SD content from http://www.emuline.org/topic/1628-arcade-pc-daphne-singe-singe-2-set-laser-disc/ Replace the HD M2V files with the SD versions, the same Windows Template will work.

First question: You are trying to run 4k content on a 640x480 CRT ? Or with standard video ? Try forcing the resolution by adding: '-x 640 -y 480' to the end of the .bat file arguments.

4K Badlands:

Massive thanks to @Nit3H8wk for his time and knowledge, 4K Badlands: 4K Badlands M2V https://mega.nz/file/sgd21R5C#J-S_QvQ6TaF4xmGGGKh6_2HFhDM1gjL5BWSa3Rjddlw Windows template (Requires the 4K M2V) https://mega.nz/folder/t082hTgT#J9NiuIB9bl2pYSbj-jrjnQ Other HD M2V (shared folder): https://mega.nz/folder/YhFTVYCY#aCVLZHBj5rM951zzk-7nfg

Not that I am aware of. But if anyone has the inclination, software and processing power to run the Daphne video through Topaz, it will play in Hypseus. I would love to get more Daphne videos upscaled to 4k, if anyone willing to volunteer ?

@phasermaniac This was an attempt to work-a-round the 'relative' mouse issues as far as I can make out. It created a ('Sinden' like) pseudo border around the edge of the window (but not as obvious), which was used to determine the edge of the screen. 'Absolute' mouse support was never released in Singe, I have seen code where it was attempted but not released. (To be honest I have not looked at Singe 2 source code). This input method is restricted to the dimensions of the window resolution, like a touchpad. I didn't use a lightgun in original Singe, as it never worked correctly in Linux, so will leave the comparisons to others. Reports thus far have been the target is dead on. The distinction of mouse input types is explained well in this thread: https://github.com/libretro/RetroArch/issues/5215 Well these are fan created games, and are not based around the actual ROM images from the arcade games. Singe has always been like this: 'best effort'. You are always welcome to learn a little LUA language and propose fixes. There were some serious issue in LBH LUA, I played through and fixed as many as I could find and put the fixed LUA for this, and other, Singe 1 games in my repo: https://github.com/DirtBagXon/hypseus_singe_data Maybe they are too busy contributing to the Doomsday Project As explained above, MAME, and Amiga Emulators, will use the arcade ROM's, so will give accurate arcade conversions, like Daphne. But this is some serious low level analysing of ROM memory, determining old CPU calls and coding the emulation of them. You will not get better than that, (unless playing original arcade hardware) - If/when it happens. Until then we have Singe, especially for the Raspberry Pi community....

@Moksi If aimtrack registers as a 'Mouse' input, it should just now work. 'Absolute' mouse device input has been added, different to how a normal 'Relative' mouse sends input. This is required for accurate cursor placement for lightguns and other touch devices. This was never present in the original Singe, and has to be activated with the '-manymouse' argument in Hypseus Singe.

@Moksi Accuracy: According to a user in the GitHub repo, lightgun accuracy is spot on using the Sinden - DolphinBar also confirmed using the -manymouse argument: https://github.com/DirtBagXon/hypseus-singe/discussions/21

hypseus-singe v2.6.14 This release adds absolute (EV_ABS) mouse input support to Singe. This allows DolphinBar/WiiMote, and other lightguns, to observe resolutions correctly. DolphinBar works out of the box in Mode 1 or 2 Sinden gun works out of the box, see button configuration discussion on GitHub Enable in Singe arguments with -manymouse New .bat files are provided in the repo zip file with ManyMouse activated.

Look in the 'hypinput.ini' file in the same folder - it is the replacement for 'dapinput.ini' [KEYBOARD] KEY_UP = SDLK_UP 0 0 -002 KEY_DOWN = SDLK_DOWN 0 0 +002 KEY_LEFT = SDLK_LEFT 0 0 -001 KEY_RIGHT = SDLK_RIGHT 0 0 +001 KEY_COIN1 = SDLK_5 0 0 KEY_COIN2 = SDLK_6 0 0 KEY_START1 = SDLK_1 0 0 KEY_START2 = SDLK_2 0 0 KEY_BUTTON1 = SDLK_LCTRL 0 0 KEY_BUTTON2 = SDLK_LALT 0 0 KEY_BUTTON3 = SDLK_SPACE 0 0 KEY_SKILL1 = SDLK_LSHIFT 0 0 KEY_SKILL2 = SDLK_z 0 0 KEY_SKILL3 = SDLK_x 0 0 KEY_SERVICE = SDLK_9 0 0 KEY_TEST = SDLK_F2 0 0 KEY_RESET = SDLK_0 0 0 KEY_SCREENSHOT = SDLK_F12 0 0 KEY_QUIT = SDLK_ESCAPE 0 0 KEY_PAUSE = SDLK_p 0 0 KEY_CONSOLE = SDLK_BACKSLASH 0 0 KEY_TILT = SDLK_t 0 0 END Note: Cobra Command uses a different config file called 'flightkey.ini' (below) - This reverses the UP/DOWN button and joystick axis. [KEYBOARD] KEY_UP = SDLK_DOWN 0 0 +002 KEY_DOWN = SDLK_UP 0 0 -002 KEY_LEFT = SDLK_LEFT 0 0 -001 KEY_RIGHT = SDLK_RIGHT 0 0 +001 ... END Thayer's Quest has it's own keyboard layout: Joystick buttons: You will need to add Joystick button config yourself, as every joystick is different. This will be the third (3rd) number, currently '0', on the button entries. Further details are in the link to the config above. Example: Joystick button 1 on your first joystick, assigned to KEY_START1 would look like this: KEY_START1 = SDLK_1 0 002 Since 0 is reserved for special meaning, joystick button 0 is identified as 1. Button 1 is identified as 2, and so on - Read here again if this doesn't make sense. This tool, might help in figuring out joystick button/axis numbers in SDL2 within Windows: https://generalarcade.com/gamepadtool/ This on-line tool might also be useful: https://gamepad-tester.com/ But remember to add +1 to the button number in 'hypinput.ini'. This is a config style inherited from Daphne.....

No, it works in Hypseus Singe, a Daphne replacement. Using the original arcade ROM set. Follow the link for more details.

Oh ok, It will be interesting to see your findings there....

Accuracy - what version of Hypseus are you running ? I just tested via remote desktop to ensure mouse alignment, and it was spot on in version 2.6.12. Earlier versions could have some issues. Also, ensure you checkout this repo, for sprite alignment improvements (although optional): https://github.com/DirtBagXon/hypseus_singe_data Test Menu, you mean Service Screen ? Pressing 9 ? Can you show the error from the command prompt when this fails ? Or the latest logfile in the logs sub folder...
