I've played Road Prosecutor for SNES. The video is extremely good. It's made specifically for a certain type of flash cart with a powerful DSP chip that is probably more powerful than every chip in a SNES by several orders of magnitude. I don't remember which flash cart it is exactly, but my friend brought it to my house and we both played it. Its way beyond anything the SNES could do on its own, especially contemporaneously since the cart size would have been ridiculously huge by the standards of the day.
Regarding the whole idea of making LDs:
You aren't the first person to want to make LDs. There are many fans of LD in general (a surprising number of them didn't get into LD until it was dead for a decade) who want LDs. There has been a fair amount of discussion about this at lddb.com with some quite knowledgeable people contributing. The consensus is that the most realistic goal, but still quite difficult, is to press a CDV. The reason this is realistic is because if you can just get the stamper made then it can be pressed any anyplace that makes CDs, DVDs, and Blurays. Pressing a 12" disc is way more difficult because there probably isn't a single functioning LD press in the world and building would cost several hundred thousand bucks.
As for CDV, yes, its analog video. Its LD video. If it wasn't analog LD video then they wouldn't play in LD players from the 80s. The format is unique in that the center portions of the disc, the ones that would be where the label is on a 12/8" LD, are CDDA audio so the disc will play like a regular CD in a regular CD player. The video portion is only useable on a LD player. In an LD player the video plays first even though it's second physically. There is also an all video 5" format known as VSD which only has the video. I've never seen one of these but they must spin at a RPM that is f*cking ridiculous at the center because a CDV hauls major ass and often vibrates the shit out of players and those play 2cm more outbound than VSDs do.
So anyway, getting a CDR drive to burn analog video is technically possible but requires a very high level of expertise in how CD drives work. CDR drives only burn set lengths of pits and lands corresponding to digital ones and zeroes. LDs use constantly variable lengths to generate a sinusoidal wave which represents composite video but also has modulated within it analog video, digital video, digital frame information. Encoded into the analog audio part of the signal sometimes is a further disguised, AC-3 encoded, Dolby Digital 5.1 audio stream. When hacking, changing, making, digital shit the task might be difficult but its also a bit straightforward. There are things like error correction, header tags, obvious file structures, etc. With analog video everything is in flux. There are no absolutes. LD video was around for 25 years and while some perfect discs were made by the early 90s it was never really perfected industry-wide. There were always random quality fluctuations and bad decisions even on discs made by multi-million dollar companies in 2001.
Many game projects were difficult to pull off. Decrypting CPS2 for example, or figuring out all the memory mappers for Famicom. However, Famicom carts only do one thing; play Famicom games. Their construction betrays their function and once you correctly dump the ROM its all downhill from there. LD and LA are a whole different animal. You can't make a flash card for it. You can't edit a portion of it and run it to see what happens. LD was a decades long format that was constantly changing and heavily invested into by really really smart dudes at Pioneer and purchased by customers well off enough to fund all this work. Some things are easier to replicate with todays tech but a lot of it is nearly impossible for even the smartest dudes. The dudes that made a FC game knew or had understanding of every single bit of data that ended up on the cart. With analog formats you can record things even if you don't have equipment sensitive enough to see every aspect of the signal. You debug it by watching it on the TV.
