Super Saver

Sunday, December 31st, 2006

Cortex v0.70 is here, now with added saving. There were still a few things that needed to be ironed out, but it now seems to be nicely functional.

I wouldn’t really recommend using it on your main PM until a few other people have tested it, though. I’m fairly confident that it won’t overwrite data from other games, but it’s still early days and there could easily be a bug or two lurking.

The old version is still available if you don’t want to risk it.

Incidentally, I decided to share one slot for all my games, given that there are only six (and a bit?) of them. Assuming I ever write anything else for the PM.

EEPROM Browser

Saturday, December 30th, 2006

I’ve been working on a few sub-projects for the Pokemon Mini on and off for a while, and two of them have come together over the Christmas break to result in the EEPROM Browser, which, while maybe not inherently exciting, does mean that I will soon be able to save the progress from Cortex, one of the two major outstanding features (along with sound).

The PM saves games to an internal 8k EEPROM, and although quite a bit was known about it, no-one had really managed to use it until now. I still need to figure out how to write to it, but I think the browser has unlocked some of the mysteries for me. There is source included in the zip, but I’ll try to write up something proper before too long.

The other mini-project was the 3×5 font used in the browser (4×6 including the spacing). This allows 24×10 characters on the screen, which is almost a reasonable amount of text. The bin file included with the source contains the 96 characters from space (0×20) through to erm, another space (0×7f), and the source contains some functions to draw them.

Cortex in New Version Shock

Sunday, July 9th, 2006

Yes, the first bearable weekend weather in a while, and a rash promise to Lupin, mean that I have indeed released an update of Cortex.
If I can even remember how to do links, you should be able to get version 0.61 here.
The main change is the new front-end, including a level selection screen and instructions. It seems to be working pretty well, and it led me to discover two nasty bugs in the game code, but there are still a few more things I’d like to add.
The two biggies – sound and saving – are also still not done, but hey, at least the project is alive.

Flash Cart

Sunday, January 15th, 2006

Long time no update. I have been working on something, but I still haven’t really decided where to keep it, so I’ve kept quiet about it.
Anyway, back on Cortex, I have now received a Flash cart and programmer from Lupin, which means I can finally get to work on the sound and saves. Maybe that will drive me to get the game completed.

Jim’ll Fix It

Monday, August 8th, 2005

I have uploaded a fixed version of Cortex for the Pokemon Mini, at the same address as before, following Lupin’s tests on real hardware.
Version 0.53 fixes the scrolling, spreads the heaviest calculations over several frames, fixes a map bug and a few other things.
The step counter and best scores and the level selection screen are the main things remaining to be done, along with a fair bit of sharpening up on the UI and general friendliness. I wonder how much I can do before my attention is again distracted by something shiny.

State of Play

Saturday, July 30th, 2005

The Pokemon Mini version of Cortex was well underway before I decided what to do about a website, and has been playable for a couple of weeks now. I used the magic of deadlines to motivate myself, by deciding to demonstrate the game at the Coders’ Workshop Meet on the 16th July.
Here’s the screenshot from Pokeme (with added border):
Pokemon Mini version
It can be downloaded from the Cortex page, until I think of a better way to manage the downloads.
It should be fully playable, but there are a few things that need tidying up, and still to be added are the selection screen; move counter and records; sound and music (both absent from the original); and possibly instructions and stuff.
