It would be a waste to replicate the entire engine across multiple banks!


well, the reality is, i don't actually need (or want) 16x the amount of data, so it's going to be wasted one way or another.

i'd rather waste it the way that costs me zero development time.

a quick and rough calculation we made showed us we should definitely be able to do all the levels we want, and maybe a few other things, even with repeated engines.

ld65 does not support pasting a segment to multiple places.

That's good to know, and rules out a dead end. :beer: But just for clarity, it doesn't make the venture impossible with ca/ld as sole tools. Pubby:s example demonstrates that you can .repeat any other command (which includes other directives [1]), so .repeat-ing a .segment (requires generating new names) basically means the assembler will lay down copies of a segment which the linker can then organize at different origins/in different banks.

pinobatch/bnrom-template is up, demonstrating interbank function calls and interbank NMI using a 256-byte fixed bank.

My GNROM-like adventures consist on myself creating NROMs and then creating the master ROM extracting binaries, pasting them together in the right order, and adding a header. And works great. I can share my humble tools. INL's oversize mapper 11 has 16x32K PRG and 16x8K CHR, which is space aplenty.

If you are replicating the engine, this "multiple NROM" approach works quite right.

For communication, I reserve a small RAM area which I don't clear on startup, plus a simple CRC-like technique to detect a wrong bank paged in (for example, on powerup).

I got around to playing your Project Blue demo. I must say I really liked the game!

Here is a video of me playing the game.

Project Blue Video

I like the idea of these puzzle-action like rooms with very precise movements. Please note that there is some cursing in the video though. I couldn't find any glitches or bugs so far.

I do have some suggestions:

- Allow the player to shoot in 8 directions. Up, down, left, right, diagonals.

- Allow shooting on ladders.

- Make the jump just a little higher.

- Put in blocks which are checkpoints so that the player visually can see themselves get to the checkpoints.

- There were a few spots in the game which felt unfair. As if I was forced to take damage.

Thanks for reading.

thanks for your comments, and the video, i appreciate it (though i have not watched the whole thing, it is great to see people interact with the game for the first time!)

i'll consider finding a way to make this happen.

while i've never beaten the entire level without taking damage, i assure you it's possible to get through every area without being hit! that said, there are certainly many areas where it's difficult not to be hit. we tried to place a lot of hearts to even this out. from the first few minutes of the video you seemed to progressing about at the pace i would hope for a new player.

Thanks for playing, erickbrox! It's always good to see a video recording. The yield is a bit different from taking notes while others are playing your game. :)

"Action puzzler", like you labeled it in the video, is actually quite adequate as a description, even if the stakes are generally lower than in a true puzzler (ie you don't need to solve every puzzle in order to pass, or may be able to make up for not solving the puzzle with platforming skills and reflexes).

It was quite the nailbiter/release to watch when you solved the room with the mechanism you had initially had forgotten about. :D

Since the acceleration physics has been tightened a bit since the submission to be snappier than mario (a good reference point), i think you'll be happy to know that it is easier to achieve the max jump height when starting to run. Put differently, the sprint stretch you need in order to reach max jump height is considerably shorter (again, shorter than super mario bros).

Oh, and while the rooms are designed around not being able to shoot from ladders, there's actually a secret technique which will allow you to do precisely that. I'll leave it to you to figure it out :)

Tying into the puzzle aspect, every room definitely can be passed without taking damage, but it's as often a puzzle (often with several solutions) to solve as it is about timing or reflexes. The trickiest rooms often require both puzzling, timing and reflexes. I was impressed by how quickly you came up with a method for avoiding the sawblades coming at you in a corridor.

Overall, you seemed to have the difficulty/progression curve we had hoped for.
