Maybe it would be better to do the opposite, rescaling the whole project to 1920x1080 in the video.txt file and then having a very small pixel size, allowing you to reduce any sprite size with almost no quality loss.I was planning on posting this 10 months ago but I can't log in the website.
I was able to test my Sprite Animations in OpenBOR, but since this is created in Adobe Flash (setting to 16bit and 8bit with No Smoothing) it doesn't look good. Well it looks good on its default size but I had to shrink them (both the Sprites Images themselves and the Size of the Player)
I decided to not use OpenBOR for this project. But still, I wanted to work on Pixel Animation sometime in the future so I'm still considering OpenBOR for the same Beat-Em-Up idea.
For example, a game defined to 320x240 will make the sprites lose too much quality if rescaled to 50% of its original size, but a 1920x1080 sprite rescaled 50% still looks good at 960x540.
