You have some errors in your code so I correct what the console showed. I have also changed the code to use requestAnimationFrame. Once a gameOver status has been triggered the requestAnimationFrame will stop running and setInterval will run the drawDeath function. You also have an error in your game over text as you were missing the x and y coordinates.

Additionally I added the downPressed variable that was missing so you could restart the game.

So I have found a solution. You will first need to download the roms from http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html

Unpack the .rar file then unzip the HC Roms and Roms folders.

Next upload the folders to colab or to your Google Drive and then link it to your colab.

From here run:

Create the pygame.Rect objects before the application loop. Change the position of the rectangles in the loop when a key is pressed:

A word of warning: this style with dynamic SQL in SECURITY DEFINER functions can be elegant and convenient. But don't overuse it. Do not nest multiple levels of functions this way:

• The style is much more error prone than plain SQL.
• The context switch with SECURITY DEFINER has a price tag.
• Dynamic SQL with EXECUTE cannot save and reuse query plans.
• No "function inlining".
• And I'd rather not use it for big queries on big tables at all. The added sophistication can be a performance barrier. Like: parallelism is disabled for query plans this way.

That said, your function looks good, I see no way for SQL injection. format() is proven good to concatenate and quote values and identifiers for dynamic SQL. On the contrary, you might remove some redundancy to make it cheaper.

Function parameters offset__i and limit__i are integer. SQL injection is impossible through integer numbers, there is really no need to quote them (even though SQL allows quoted string constants for LIMIT and OFFSET). So just:

You can't. That is reserved for users only.

(See my comment under OP for context)

The error message "FrameProcessor" object is not callable means what it says on the tin: there is an object of type "FrameProcessor", and your code is trying to call this object despite the fact that this object cannot be called.

(Remember that to call something is to treat it as a function and to try to run this function, much like how you might call a parent at a grocery store and tell them to buy you a snack.)

Where does your code try to call this FrameProcessor object? Well, you yourself pointed out the line:

processed_frame = self.process_frame(sess, frame).

In Python, any time you write an expression of the form something(arg1, arg2, ...), the Python interpreter treats the expression as a function call, which, from your error message, we know we're not allowed to do if the something happens to be a FrameProcessor.

And we know from the earlier line self.process_frame = FrameProcessor() that self.process_frame is a FrameProcessor. So the problem is that you're trying to call self.process_frame like a function when it really oughtn't be called in that way.

So, how can this be fixed?

Look up the documentation for FrameProcessor, wherever that happens to be, so that you can know how FrameProcessors ought to be used. With that knowledge, you can revise the lines processed_frame = self.process_frame(sess, frame) and maybe self.process_frame = FrameProcessor() to match the intended usage, whatever that may be. At that point it's just a matter of reading and applying the relevant documentation.

EDIT:

Looking at the code for FrameProcessor, it seems the issue is caused by an extra indent before __call__ is defined. Indents determine scope in Python, and the extra indent is causing __call__ to be defined in the local scope of the __init__ function. That means that __call__ has no meaning outside the body of __init__, which is not what we want. Try removing the extra indent before __call__ and see if that solves the issue.

At the end of its memory map, the 6502 (and variants) has a vector table, at addresses $FFFA-$FFFF:

dataFile >> consolePrices[i]; on the first iteration leaves \n in the istream.

Then getline(dataFile, consoleNames[i]); extracts that new line symbol on the second iteration and you get the empty string. After that dataFile >> consolePrices[i]; tries to read int but meets the string Sega Genesis, leaves the consolePrices[i]; uninitialized and the istream in fail. Further iterations can't read the failed istream.
