ah no, no screenshot, thats my replay...i gotta get a cam =\
I'll write up a quick little tutorial like niigaki suggested. Your replay.zip is incomplete--it needs to include the entire parent folder and all of its contents. I'll edit this post when I'm finished. You should go ahead and delete that zip file from your attachments and reupload it when I'm done.
Here we go:
First, attach your PSP to your PC/Mac and go to the PSP/SAVEDATA folder. It'll list your saved files. Mine looks like this:
The folders with the "UC*S*****LCNS" prefix contain your saved Driving Challenge replays, if you saved any. These are the in-game driving challenges; the license tests. The folders with the "UC*S*****RPLY" prefix contain saved replays from single-player events. These are the ones you need to look for. The letters/numbers after the "RPLY-" in the folder are the same for each track, and the last two numbers are the number of replays you have saved for that specific track. For instance, I have 4 replays saved for the Citroen on Autumn Ring Mini Reverse, and those 4 replays are the "B963F590D" folders, incremented 00 to 03. The 03 folder is the last replay I saved for this challenge, which is my 56.1 lap. If you aren't sure which of yours is which, open one of your folders and find the PARAM.SFO file:
Open the PARAM.SFO file with a text editor like Notepad. You may have to hit Format -> Wordwrap to read it a little easier:
As you can see, it lists the course, vehicle, physics, and tires used. Do
NOT make any changes or re-save the file from your text editor--simply close it. Any changes or re-saving from the text editor will result in corrupt data.
When you've found your replay by viewing the PARAM.SFO file, go back to the SAVEDATA directory and, on a Windows machine, right-click the folder containing your replay data and choose Send to -> Compressed file. This will create the ZIP file you need. Cut and paste that zip file from your PSP to your computer. Leaving the ZIP file on your PSP won't harm it, but it will show up as corrupt data in your Saved Data Utility on the PSP's screen.
When you've placed that ZIP file on your PC, upload it to the forum using the file attachment utility, or just host it online if you have a preferred hosting solution and provide the link in your post. Other users can then open your ZIP and extract the entire folder to their PSP/SAVEDATA directory to view the replay in-game.
I mentioned the last two numbers in the folder name because there's a chance you may already have saved a replay with this folder name. If that's the case, make a backup copy of your replay folder somewhere on your PC/Mac before you unzip another user's replay to your PSP, as it will overwrite yours, and I'm pretty sure incrementing the folder name yourself by renaming it (to prevent yours from being overwritten) will again result in corrupt data.
This probably all sounds complicated, but it's super simple... takes 5 minutes at the most.
