On http://www.luaplayer.org you can get the new version 0.20. It is updated to Lua 5.1, there are some bugfixes and a new function for loading images from memory. I'll try to add pspgl the next week.

The changelog:

v0.20
==========

• updated for gcc 4.1 and Lua 5.1. Some things you need to change for 5.1:
  
  
  
  • change table iteration code: "for i, value in someTable do" to "for i, value in ipairs(someTable) do" (but use "pairs" for tables like "t={foo=bar, foobar=99}" and "ipairs" for tables like "t={foo, bar}")
    
  • it's pure Lua 5.1: no binary operators and double as number type (e.g. now you can use one number for storing IP addresses)
    
  
  
• Sound.load doesn't crash any more on invalid filenames
  
• fixed problems with daylight saving time
  
• Font:getTextSize fixed. Test case:
  

  Code:

  proportional = Font.createProportional()     proportional:setPixelSizes(0,8)     test = proportional:getTextSize('some text')     assert(test.width == 39)     assert(test.height == 6)

  
  
• blit operation from screen to image works now, e.g.:
  

  Code:

  screen:print(10, 10, "hello", Color.new(255,255,255))      image = Image.createEmpty(480, 272)      image:blit(0, 0, screen, 480, 272, 480, 272, true)

  
  and now you have an "image" with the text "hello"
  
• TTF font plotting to images now sets the alpha value to opaque, so you can write e.g. something like this for buffering texts in images:
  

  Code:

  image = Image.createEmpty(400, 200)      proportional = Font.createProportional()      proportional:setPixelSizes(0, 16)      image:fontPrint(proportional, 0, 20, 'Hello', Color.new(0, 255, 0))      screen:blit(0, 0, image)      screen:blit(3, 3, image)

  
  
• new function Image.loadFromMemory for loading images from memory:
  

  Code:

  jpegFile = io.open("test.jpg", "rb")      data = jpegFile:read("*a")      jpegFile:close()      image = Image.loadFromMemory(data)

  
  PNG and JPEG is supported and autodetected
  
• image-to-image blitting now uses alpha full blending [Callum Bethune]
  
• System.rename(oldName, newName) for renaming files and directories
