The file you linked is only 37 bytes long, so it contains no useful data. If that's the only file you have, the save is not recoverable. The only thing that might work is to use data recovery software to try to locate an old copy of the file that may have been deleted, but there's no guarantee that one exists or that it is recoverable if it does. If you are not using autosaves, it's a good idea to save regular backups of your park manually so you don't lose everything if a save gets corrupted.

No, they aren't distributing any of the original assets, but they did reverse engineer, decompile, and modify the code, which the EULA tells you not to do. It is not a clean room implementation. My point is not that I give a shit what the EULA says, I'm just saying that if the OpenRCT2 developers had followed @jensj12's advice, we wouldn't have OpenRCT2.

The RCT2 EULA also has that wording, but that didn't stop the OpenRCT2 project.

You need to enable the cheat menu in the options.

The PR also mentions that you can revert to the original pricing via a compiler flag, so you can have it be exactly the same if you want that.

Pay per ride is usually easier. You generate a steady income that's proportional to the number of rides you have - the small number of guests that might not pay anything is easily offset by the fact that most guests are spending hundreds over the time they're in the park. Coasters are highly profitable - guests will often pay £15 or even £20 for a brand new coaster, and if you're running three trains of 20-30 riders each, you're looking at upwards of £1000 income per ride cycle. In pay per entry parks, you get money when guests enter the park, but you're limited in how much you can charge because they only spawn with so much cash - and once in the park, they're spending very little. There's a soft cap on the number of guest in your park, so once your park fills up, your income becomes severely limited as new guests won't enter until existing ones leave. Therefore, it's harder to make steady profits - you either have to expand rapidly and advertise aggressively so you always have new guests coming in, or try to encourage guests to leave sooner (like by not building food stalls or toilets). You can also profit from food and drink sales, but guests won't buy food as often or pay as nearly as much as they would for rides. They won't refuse to pay for rides, but the amount that they're willing to pay for rides is a lot lower if they had to pay any amount to enter, which makes sense, although it's a bit simplistic - whether they paid £1 or £50 to enter, the amount they'll pay for rides is the same.

You must have had a very old version if that worked before - that was changed years ago.

If you want to try generating new assets with AI, go ahead. But since you still have to develop and train the AI, it's not exactly "automatic" - even if you can make it work this is still a ton of work to pull off. Every ride has its own set of peep sprites, on top of the basic set for walking, sitting etc. That's literally tens of thousands of sprites you'd have to add for every peep variant you want. Not only that, but currently, the ride sprites contain pairs of peeps - you'd have to split those in two.

You're right, it wasn't like this in the original RCT2. IIRC, this is how it was in RCT1, and the feature used to be optional but the option was eventually removed in order to simplify the code. There's no longer the option to have the vehicles displayed as separate rides like they were in vanilla.

Here's the link to their Discord server. Any questions about that server specifically should go here - I doubt the people who run that server are on this forum, and they're the only people who are likely to be able answer. They sometimes set the default role to "spectator" to prevent trolling. When they do this, you should still be able to connect, but won't be able to build unless you have been granted additional permissions. If you don't see the server in the list at all, then the server is probably down, and if you want to know why you'll have to ask the admins. If you can't connect to the server at all, first make sure you're on the right version (the Mozar servers use the release builds). If you still can't connect, check if you can connect to other servers - that way you can tell if the issue is with you or the server. If it's a problem with the server, then again only the admins are going to be able to help.

OpenRCT2 needs the RCT2 assets to run. You can either transfer the files across from a machine that does have a CD reader, or download the demo version and use that instead.

Well, if the length of the cars is indeed the issue, then reducing it should fix it, so that's the first thing I'd try. And if that works, you can submit a PR to the object repository to fix the issue. If that doesn't work, I'd compare the vanilla go kart JSON with the expansion version and look for all the differences, then test them one by one. Code to support wider radius bends was added some time ago, it just needs someone to make a sprite for it. You can hack a wide turn onto the go karts and use scenery to build the track.

I would make the RCT1 version of the car have the RCT1 limits and leave the RCT2 version as it is. All of these rides are single car IRL.

Not really, I still have all the source files, but I just can't get the sprites to look good enough (and I doubt I ever will) so I haven't done much more with it since I made that layout (except to add large half loops, but that was a side effect of implementing them for the single rail track). I might come back to it, it would be a nice track type to have but unfortunately also one of the hardest to get right. I can upload the source code and sprites if you want them.

That's by design. It's intended to operate as a shuttle coaster, the circuit is only completed because the ride type requires it. The "Insectivore" and "Tailslide" designs also function this way.

This scenery group contains custom objects - do you have those objects installed or just the scenery group? If you don't have any objects that are in the group, this would explain why none show up when you select it.

Yeah, there was a bug that caused ratings to take 255x longer to calculate, it's fixed now.

This isn't a bug - setting a higher chain lift speed makes the reliability decrease more rapidly, so setting the chain lift speed much higher than normal has the side effect of making the reliability decay much faster than normal. You can use booster pieces instead, or disable breakdowns.

Huh? If you want to play OpenRCT2, then you obviously need to get OpenRCT2. In order for OpenRCT2 to work, you also need to have the game assets - which can be obtained from either the full game or the demo version. There's no such thing as "OpenRCT2 demo".

You can run OpenRCT2 using the demo version. There is no difference between the demo and the full version if you are using OpenRCT2, because OpenRCT2 only requires the assets and ignores the executable (which is the only thing that differs). There is another demo out there that is missing assets, but the one on this site is not, as far as I'm aware.

There is none. OpenRCT2 requires the RCT2 assets to run, it doesn't matter whether you get them from the demo version or the full version.

Those last screenshots you posted make extensive use of custom scenery - almost all of the objects you see there aren't included with the vanilla game nor OpenRCT2 (currently, OpenRCT2 only adds a small handful of objects to the base game). Unless you have downloaded a park that uses these objects, or visited a server that does, or downloaded the DAT files manually, you won't have these objects available. If you want to start using custom objects, the best place to start is by downloading a custom scenery workbench that has a selection of custom objects included (and pre-selected), as picking out the objects you want and downloading them all can get very tedious otherwise. New Element has a selection of custom scenery workbenches and a very large collection of miscellaneous custom scenery objects that have been created by different people over the years.

I will probably merge more new ride types in future, not sure in what order or exactly when as I've mostly lost interest in this for now. Currently, I have yet to produce any vehicle sprites of sufficient quality to merge, which is a problem. A diesel powered coaster would be an interesting opportunity to use the engine sound effect, but other than that it's far to obscure to be a priority for me (Not that this is necessarily a problem if the ride type is sufficiently interesting - the vanilla game includes such oddities as the Hooper reverser and Skytrak, and I have considered making an Arrow pipeline).

Yes, it would be a hard job. In order to make OpenRCT2 independent of the original game, all the original graphics and sound need to be replaced. This is what was done for OpenTTD, but with OpenRCT2 there are a lot more sprites - while vehicles in OpenTTD can have as few as 8 sprites, coasters in OpenRCT2 range from several hundred to many thousands of sprites. This has been talked about for a while, but there just aren't enough people currently working on it to expect it to be done any time soon - very little progress has been made so far. If you want to help make it happen, then check out the #open-graphics channel on the OpenRCT2 discord. No, no original code remains.

As I said, it's most likely in C://Program Files (x86) if you installed RCT2 with default options. If you can't find it, try searching your hard drive for "rct2.exe" or "g1.dat" as that should take you there. There's not much point me posting pictures of my RCT2 installation as I have it installed somewhere else. No, the disk version will work fine and there is no difference.
