Creating Better Logos
Logos must be in PNG format. A good logo shows something that is representative of the game, like the game's main characters (from the title screen, for example) or other prominent art. You can also use the entire title of the game, preferably including a visual element along with it. The file must be named
logo.png and placed in your curation folder. You can add a logo to a curation in Flashpoint Core by dragging it on to the left panel above Drop an image here to add it.
Recommended tools for grabbing logos include Snip & Sketch and Paint, both included in Windows 10/11 by default. You're free to use other tools, but remember, always save logos in PNG format. When possible, it is preferable to make logos more or less square-shaped.
Removing unwanted elements from a screen
Often a button or other element pollutes the view or forces cropping more space from the image than you wanted to. You are not required to try these steps, but a better logo improves how the game will be presented in the launcher. The easiest solution when a image has a plain background is to simply cover the elements in an image editor; you can select an adjacent area of the background in Paint and stretch it to cover the element.
When a logo's artwork would look distorted by the above method, you can try ripping a suitable asset; most non-HTML5 games store images inside the game's binaries, and for Flash the JPEXS Free Flash Decompiler is an useful tool for retrieving them. In the below example, the menu image was found in JPEXS by looking into the "images" category of (in a rare occourance) an internal SWF. Right click the image and export it to your computer; you would notice this image was stored in the JPG format, so a conversion to PNG should be done later.
When a game uses multiple assets for a screen, another approach is to look at the "frames" section in JPEXS, select the frame of the screen you want to use if any and right click the unwanted elements in the left menu to remove them from the screen. Then, export the selection or take a snapshot of the frame and later close the file without saving. In this case, the character's body was separate from its face, the background and game's title, so this was an easier solution.
