I don't see any reports of issues on IA. But check GitHub to be sure if you want to be certain you have latest LUA. There have been reports that the Taito LD Game Collection version of Hayate is over-saturated in red color, looking again, I personally have to agree.

I hope you do v1 as overlay is more authentic:

Which overlay version are you looking to do, there seem to be multiple versions? An archive seems to be on IA with recent upload dates. https://archive.org/details/singev1-hayate https://archive.org/details/hypseus_singe_hayate-hd

Having experimented with creating video for Daphne/Hypseus in the past, it's all about frame accuracy and maintaining FPS. So cropping the (it appears) first 157 frames of video, and the appropriate edit to the audio, (you can perhaps use the existing .ogg file as it should match), then it should (in theory) work in Hypseus. Basically look to match the existing MPEG2 video frames, as that IA MPEG2 seems to have been done by someone who figured it out. There are ffmpeg commands on how to correctly encode the .m2v and .ogg for Daphne and Hypseus on the Hypseus game LUA GitHub pages. So that would be my starting point. But ultimately testing the video files in the game and carefully watching scene changes are the way to be certain.

Here's another interesting source I just found. https://archive.org/details/youtube-HMtN7cIlMYk But it's already MP4 from 2 known existing prototype laserdiscs (alleged). Now this gets interesting, as the frames/scenes may not necessarily be in the same order as the Limited Edition footage. But parts of this could be used to reconstruct the prototype footage. But it's gonna take lots of time and dedication to match it to the LE frames, which will be required in order to play on the dle21 ROM from the DLP site. Note this ROM plays in Daphne and Hypseus, not just Dexter as the page states. You wanted a restoration task, well here it is... Let's see who actually picks it up.

You can do want you want in the transfer, include disregarding the lead-in frames. The 8 minutes of "prototype" footage was discarded decades ago and only (re)discovered on VHS for the Limited Edition, that VHS footage was tagged onto the end of the original laserdisc. Hence it looks like, well a VHS capture. Because it is. No other known capture exists as yet, I believe, it was used to reconstruct the early game as detailed on the DLP: https://www.dragons-lair-project.com/tech/enhancements/dle2x_prototype_mode.asp

Not only YUV4MPEG2, but the decode also contains the pseudo lead-in from the presumed spin-up on the LDF capture, which means the starting frames are way off and need to be edited out. There are 55544 frames in your decode, whereas the disk only should have 55387, so you've picked up 157 invalid frames at the start of the mkv that completely mess up scene alignments.

I think you are talking about "drop-outs" rather than "skips". Unless your ld-decode methodology is flawed or underpowered. And there are certainly "drop-outs" in this capture, you can clearly see them in the video I posted above. In order to attempt to remedy this, the (DomesDay) process is called "stacking" where you basically "compare" multiple disk captures (you really need a minimum of 4 captures, from 4 different disks) and if a defect is detected, the other members of the "stack" are checked. If the defect is on all of them, it's a mastering error, if it's not then it's a capture defect and is discarded from that source and the other source members are used for that frame. Ultimately it's all about maintaining the best "perfect" frames and framerate to ensure your end result is a playable media on real hardware, or in true emulation. The current single capture seems to play fine and is frame accurate in the MPEG as far as I am able to tell on all the scene skips (i.e. no "skips" as frames are accurate). It may be a little premature to start working from a single exported LDF sources, with lossless conversions (it's actually lossy) from radio frequency analog sources to digital MKV. For stacking to occur, you will always have to refer back to the LDF/TBC RF captures. As only 400 copies of this LE disk were produced and who knows how may no-rotted copies remain, it might be a long or even fruitless wait. If you just wanna work from "the best we currently have" then sure, use the current single source, ultimately you are altering the source material with your cleanup in any case, so no purist is ever going to want to use it, lossless or not, and it certainly won't be accepted in MAME. But in lesser emulators it should be a great addition. DomesDay documentation is very well written.

You mean you ran it through "ld-decode --NTSC --V4300D_notch_filter" to produce a .mkv as described on the IA LDF source page. Well I guess that'll save a few decode hours for anyone with a potato PC, although the time to download it will probably make up for that - 🤣. Look forward to the end "enhanced" results, which should ultimately be "playable".

Where there is a DomeDay RIP there is a DomesDay LDF source. 30s of searching and, as if by magic: https://archive.org/details/dragons-lair-enhanced-limited-edition-laserdisc-ntsc The source is noted on the MPEG2 page.

It's available from the laserdisc DomesDay rip here: https://archive.org/details/DomesDay_DragonsLairLE Played here:

Just put all the Frameworks in the same folder as the Singe games. But don't add .hypseus to them. Better yet, now use the new Zip ROM format in v2.11.6 and you can put the files anywhere you like and don't have to worry about those Framework folders any longer..

The game extension used for RetroBat was recently changed from .daphne to .hypseus. I would start looking there firstly if this is using all the latest distributions. Check RetroBat docs, or talk to the guys on Discord. There was some recent chatter about RetroBat changes on there recently.

Has anyone got the DomesDay media from Spaces Ace and Dragon's Lair LE 2002 laserdisc with the prototype footage ? I found on Internet Archive.

This link seems to have all the 4K Daphne games video: https://mega.nz/folder/jMkxzBgT#FSFJhqXLUJ_qZsd0lTTg5A
