Mycket trevligt!

It's a difficult one to get by, no wonder the price tag.

@Yosikuma Yes.

@MikeblokeGreat work! I have thought about making "Fire Attack!" since it was my first handheld. Will you continue and finish it as well as you can or do you leave it as it currently is?

I'm missing a few parts but I could look into it.

Seen it before, it's a boring but perhaps uncommon box, worth collecting.

I don't think we'll see any more development on this one, recommend BackBit as an alternative.

Not sure what you have in yours, they're often four loose diodes soldered to the board.

It's a 7812, 12V regulator. Check diodes as well, they go pretty hot.

I experimented with stealing frames from Leaderboard on the C64 emulator WinVICE. I took half the frames and made a set of 16 and changed to Channel F colors. Then wrote a cmd program in C++ to filter just the changes from a previous image and got a set of black bmp-images with a little colored scribble on them. Had to take the size down a little and shrink height as the Channel F pixels are tall. ... ... Stripped the header of the bmp-file and translated the index colors for green, red, blue, background and clear into 0, 4, 8, C and F (because colors set into ports corresponds to $00, $40, $80 and $C0). The conversion program does both the bmp preview of the frame change and the binary file with the Channel F image data, just drag and drop two files (equal in size, my palette layout). So I now have graphics data with two pixels per byte that I can draw with my new nibbledraw code (very small changes to "multiblit"). For clear it just skips the pixeldata transfer, so present graphics stay there, just like the "blit" code does if "clear" color is set. It's slightly faster than "multiblit", as it doesn't need to decode colors from two bits - but it requires double as much data (which is normally not a problem). My example could easily have the graphics compressed (should there be a need for it) a lot with a simple routine and unpacked to RAM, there's a lot of empty space in the frames. Move controller in a direction to swing - it's just the hitting, nothing else fun (yet). Having the courses drawn up from polygon data would have been really neat... 2023-09-11_38_14_Leaderboard.bin

I'm selling two Multi-Carts for $150, it's the last two I have chips for atm. Need to raise $300 for car repairs (left back wheel bearing). I'll give you guys a chance to reply before I shout out about it. About 2 weeks before delivery, so no long waiting times. Let me know.

I guess you'll be careful the second time...

.... everyone needs to get a BackBit... it's actually cheaper $134 with the adapter. I would need to pay $8 fee and 34$ tax - and $20 shipping - so only $196, feels like it will never happen. 😢 I could ask a friend to ship it though - and save $42 by escaping tax... https://store.backbit.io/product/backbit-pro/ If anyone feels the need to sponsor me with a BackBit I'll make a proper Channel F cart shell 3D drawing for 3D print. That baton she's come up with is an eye sore. BUT, some nice design to put on the shelf, increasing the Channel F library IS pretty nice.

Maybe some kind of collection cartridge should be made with all the unreleased games...?

There should be a proper shell made for the backbit to fit better. Instead of the "handy to move around between systems"-option a more permanent design would be nice. Something larger, videocart-looking to dock into or a replacement shell entirely for the backbit. I might get one as well if I happen to fall into a pit of money. Why are the binaries 2046 bytes and not 2048? Only took a quick look, hoping to get a game in later.

I'd try reseating/swap places of the VRAM but first option is probably to check cart holder and connection - and voltages. Reseating/cleaning the other socketed chips is also a good idea.

If you use the "MESS adjusted" plot routine it adds 4 to the coordinates (4,4 is the upper left corner visible in MESS) so that would explain a change for a 122 width block placed at "0". You change bg colors just as described in the links. You can only set one color per row, don't think it's possible to switch fast enough to force more - nor time it. I recommend drawing background larger than "0,0 102,58" as different TV:s show more of the screen than MESS does. Going -4,-4 106,60 is not a bad idea (or change routines to use real coordinates).

For a single line you'll write $0 or $FF in the proper row at columns 125 and 126 https://channelf.se/veswiki/index.php?title=Accessing_VRAM For severeal rows it can be handy to define an object to plot with the usual blit routine. https://channelf.se/veswiki/index.php?title=Palette Using grey/blue you can toggle to black with a single write. To get white you must fill with foreground pixels, any of the colors, they're white if the line is set to b/w mode.

No... the hovering looked odd, this is better, a sliding kind of motion. I like the collision detection, it's very forgiving - just enough. Looks like the fish moves sideways above the surface of the water when changing to a start position close to the end position. Speed at 20 is very doable, didn't have the stamina to play longer. Ideas: Maybe more fish? Maybe fish could have gravity where you move one pixel at the top and increase jumps at the lower part. What if fish moved past the screen bottom instead of disappearing and reappearing above the water surface (masking it on it's way down through the water is perhaps too much work - as well as a splash effect). If standing still too long a fish could go straight for him - or maybe he could loose the grip.

If anyone impatient has been thinking about getting a cart I currently have nothing waiting. Currently, any new orders will be shipped within a week.

@3DMAZE We're all rooting for you to pick up development, are there still plans and maybe a deadline/goal? With minor reset-fixable quirks almost everything runs for NTSC, how about going for that and leave the compatibility-fixes for PAL to someone else? I estimate 90% of the users will be using US machines anyway.
