To complete this - i started a new try:
- uninstalled rct
- installed rct
- started original rct.exe and changed resolution to 800x600 and quit
- started the modified version (1280x720) - this one "crashed" immediately to windowed mode...
as seen in the readme from gog with the unpacked.exe: "Make sure your monitor supports the resolution you are trying to run the game (say, 1280x720), otherwise it will revert back to 640x480."
- i used again the unpacked.exe, changed the hex-values to 1280x720 - this worked for me! This resoluion is therefore supported by my system (normaly i have 1920x1080).
Well, with 1280x720 the game fully fills my monitor. Now i use this to play the game. :-)
Thanks Splatsch! :-)
Hi again, a lot of time later !
I have tried again using another computer and I encoutered the same problem as yours with my french version (which I didn't encountered on my previous main computer)... And I think I understood what's the problem
: if you change the name of "RCT.EXE", the game will launch in a window, no matter what you do (even if you only do a copy of the basic .exe : for example "RCT - Copie.EXE" will automatically launch in a window even if it hasn't been modified). I don't understand WHY (computer's science), but it seems to be the problem for me. So I simply modified the original RCT.EXE and directly saved it, without creating a new file, overwriting the original. And it works.
May be for the english version, there isn't this "restriction" of the executable's filename for the game to launch correctly...
If you haven't changed your executable's filename, then forgot what I said ;) (even if it's that who solve the situation for me)
It's just in case it could help some people.
By the way, if people look for the method of the hack, here is the source : WSGF's page
, which works (widescreen or window hack) with GOG's version : I installed the french version with the latest installer and directly modified RCT.EXE in the instal directory, and I can play in 1280x720 in fullscreen in french.
And there is something new here
: someone created a hack that, I quote : "It basically puts the hexedited game into fullscreen in native resolution.
". I tried it with one (french) version of the game hacked for window mode : it seems to work.
When I try the Hack by my the installed RCT.EXE it just runs in 640x480. But when I try the same Hack on the unpacked.exe in the Link below it workes fine, but change the language of the game from english to german. I am using the last Version of RCT and my System is Win 8.1
I'm not sure that I'll be able to help you, especially if it's maybe windows 8.1 related :/ It's a lot of reading, but I suggest you to take a look at what we discussed along the thread if you already haven't, may be you'll find an answer ?
I wish you good luck ;)
Edit : And someone need explanations concerning how to use the Hex Editor, please see here
