PSP Casio MG-880 Calculator Game - Digi Invaders

I have made a version of the old Casio Calculator MG-880 game for the PSP.  I wanted to include custom backgrounds for the game and a hi-score system, but unfortunately due to the PSP's Flash and Memory limitations I couldn't do those things.  However I did include 3 lives in this version, as opposed to the 1 life in the PC version I made previously, and I have released a few different flavoured versions of the game (see the screenshots below.)

Controls are (you play the game by turning the PSP sideways):

   UP Arrow - Aim
   DOWN Arrow - Fire
   X Button - Start Game

Click on one of the game links below to Save the zip file to your computer, un-zip it and then place the game in any directory on you PSP and then use your PSP browser to Open the file.  Each version of the game is between 170 - 220 KB in size.

Here is an example of the address you would enter if the game was placed in a Flash folder in the root directory of your PSP memory card:

   file:/flash/mg880-01.swf

Right-Click on one of the flavours of the game to Save-As (unless you want a large version of the game to pop up on your screen):

I don't understand this game. Just numbers coming up on the calculator screen. And when you press the up or down arrow a number on the calculator screen increases or decreases. How do you play it? Please tell me.

Re: PSP Casio MG-880 Calculator Game - Digi Invaders

Sorry 'bout that rollinroll.

It's a copy of a very old calculator game that I used to play when I was at school.  Basically it's supposed to be like Space Invaders.

What you do is use the UP arrow to change your BASE to match any number, or INVADER, that is advancing towards you.  Once you change your Base to that Invader number you press the DOWN arrow to destroy the Invader.

If you destroy 2 or more Invaders in a row that add up to 10, 20, 30 etc then you get a 'n', or Mother Ship, advancing towards you which you can then destroy for 150 points.

The closer the the right hand side of the screen the Invaders are when you destroy them the more points you get for each, eg. 80 points for an Invader in the first position on the right, then less 10 points each position closer to your Base (ie. 70, 60, 50, 40, 30, 20, 10.)

You have 3 lives which are displayed next to you by 3 lines next to your Base.

The game has 9 levels and each level the Invaders advance faster towards you.  Once you get past the 9th level it goes back to level 1.  It's pretty hard to get through the 7th, 8th or 9th levels though so it can take a while to do this.

Anyway, I hope this has helped.  smile

Re: PSP Casio MG-880 Calculator Game - Digi Invaders

Thanks for the help! Now i understand. A very old game rewritten in to flash. Very simple but yet fun and challenging. But there's one thing i didnt like about it, it has no score system. Anyways, good job!

Re: PSP Casio MG-880 Calculator Game - Digi Invaders

Thanks for that, I'm glad you like it.  I am only just getting used to writing in Actionscript, the only other language I've written in is BASIC on my old Commodore 64.

I did a 10 day Flash course and they touched on Actionscript but didn't get into great depth.  I have only been learning things by downloading Flash games and looking at th code.

I tried a way of saving/loading a hi-score with this game but the PSP Browser wouldn't come to the party.  If you can tell me how to do it then I will try to put it in the game.

Thanks again.  smile

Re: PSP Casio MG-880 Calculator Game - Digi Invaders

Well, what i meant is to just have the flash game tell you what score you got, on gameover. Like, on the calculator screen it stands "Game Over - Score: blabla". Have a variable that holds the score and increase the variable when you destroy a number and display the variable on the calculator screen when you get game over.
