Beeblebrox Posted October 11, 2022 Share Posted October 11, 2022 5 hours ago, bfollowell said: So, this engine is pretty much identical to the C64 version? So, that begs the question, is the fall rate different between the C64 version and the original A8 version? If we have a lot of people that only played the original A8 version, and not the C64 version for comparison, that may be where the perceived difference in the fall rate is coming from. No worries. What I was actually getting at was why is the original 80's game fall rate so slow? Quote Link to comment Share on other sites More sharing options...
Rybags Posted October 12, 2022 Share Posted October 12, 2022 C64 pixel aspect ratio is skinnier than Atari so movement will probably appear more consistent there with fast X/slow Y. What bothers me more than the fall rate is the slow climbing. The fall rate is probably deliberately slow to force you to time jumps/falls better. If it was twice as fast then you'd have much less chance of being zapped on the way down. Quote Link to comment Share on other sites More sharing options...
adam242 Posted October 12, 2022 Share Posted October 12, 2022 If I let the game sit long enough for the 'attract mode' color cycling to kick in, the PMGs get corrupted. All returns to normal when I resume playing, though. Also, and unrelated, is the 'chase rate' of the deadly floor dots the same as in the original Bruce Lee? I seem to recall that in the original game (the Atari version at least), they were slightly faster than Bruce and would catch up if you didn't time things correctly. In Return of Fury, he can stay ahead of them. 1 Quote Link to comment Share on other sites More sharing options...

Why is falling so slow in this game? Bitd was it intentional as part of the gameplay or was it just related to cpu cycles? One of my favourite A8 games from the 80s is Alley cat which is fast and has some amazing momentum in the character movement, gravity and gameplay. So it was possible at the time. I'd loved to see this classic retain all it's identity but without the wait of a good few seconds when falling either small or big drops. It just seems unnecessary if it's avoidable. 😁 The fall speed is the same on both the Atari 800 and Commodore 64 versions. I have both. Also the Atari version was programmed first, then ported to the C64. Quote Link to comment Share on other sites More sharing options...

Rybags Posted October 12, 2022 Share Posted October 12, 2022 I've noticed the "chase dots" early on are a different speed. From memory on the original (and probably here) your foot speed can actually vary depending on how "deep" you are in some terrain - jumping, landing or just walking onto things can affect that.

devwebcl Posted October 12, 2022 Share Posted October 12, 2022 (edited) The original playability of the game is what I like about it. I found a peculiar bug where Bruce can hit Yamo easily, as we can see in the video. Edited October 12, 2022 by devwebcl Quote Link to comment Share on other sites More sharing options...

That's a weird one, it's sort of registering a hit but yet after the two hits Yamo does not respawn, he just keeps on getting hit. Also it might be worth noting that some bugs may be from the C64 version (sorry dmx) so not produced by the Atari build....Maybe...

Yes, this is because I am reusing the Yamo player 4 times as a mask, combined with PRIOR register value to give other hues. So technically you are falling on Yamo by doing that. The other possibility for extra colors is to change the registers on the fly like the example below: But you can see other problems with this method, not to mention it's a real timing nightmare: pha txa pha lda #$83 sta COLPF3 lda #$45 sta COLPF2 ldx #$0E ;Loops sta WSYNC nop nop sta WSYNC :4 nop loopColors :6 nop lda #$CA sta COLPF2 lda #$66 sta COLPF2 lda #$2C sta COLPF3 lda #$39 sta COLPF2 lda #$83 sta COLPF3 lda #$45 sta COLPF2 dex ;sta WSYNC ;:2 nop bne loopColors lda #$00 sta COLPF3 jmp SetNextDLI And the final problem with this method is the resulting vine/moving ladder: For this particular situation there just isn't a lot of options. 3 Quote Link to comment Share on other sites More sharing options...
woj Posted October 12, 2022 Share Posted October 12, 2022 Time to contribute something, for those of you that miss the XEX version for quick loading from carts of different kinds, attached the Tix one (yet to try it on my real hardware, currently my SD card reader is unavailable to copy it to the card and try with SIDE3, but I did try it on Altirra with Side3 emulation).

woj Posted October 13, 2022 Share Posted October 13, 2022 I was asked for also the classic sprite version, though that's what @Ute posted, I guess the request was to have it with the title screen and all, so here it goes.

dmx Posted October 13, 2022 Share Posted October 13, 2022 On 10/11/2022 at 11:35 PM, Ute said: I have no idea as I've never looked at the C64 code. I would guess the original author(RJF) ported most of the mainline 6502 code from the Atari to the C64, line for line, except where custom chips come in to play. Whether or not that translates to the exact pixel by pixel movement speed on a completely different machine, I'm going to guess it does not. As far as what DMX has done, I don't think he changed the fall speed from the original C64 Bruce Lee. No, unless DMX changed the fall speed, but I doubt it as the C64 still has the 'floating down' effect. I'm not sure I understand your meaning. If they only played the A8 version, they wouldn't know any different. As far as ROF(A8) and the original Bruce Lee(A8), it's the exact same fall speed. EDIT: I think you're confusing Bruce Lee 2 with ROF - In Bruce Lee 2 the fall speeds are a lot faster. If people want another installment of Bruce Lee in the future I would be willing to change fall speed, jump distance, jump height, screen resolution, etc. But again, since this was a port from another machine, preservation of those ideas was the objective here - as much as was possible. Nope, didn't change the fall speed. In fact, I only ported over labels from the C64 version, the Atari version is not based on the same code, but the original, which I didn't disassemble. So it should be all-original. RJF did indeed port over the Atari code to the C64. The C64 version's logic only runs every 3rd frame, btw. So RJF probably increased the movement speeds.

wesmond Posted October 13, 2022 Share Posted October 13, 2022 (edited) Hi all, I'm having an odd problem playing both versions in latest Altirra (tried both the 4.01 release, and 4.10 test 21) - I have my joystick mapped to cursor keys, and left control. Every time I press a cursor key, the game goes into "PAUSED" mode. If I then press the same key and hold, it's ok and I can run for a bit, but if I stop and start again, or change of direction, it PAUSEs again... Must be something in my config as I guess some of you have already played it on Altirra? I've tried the raw/cooked/full scan keyboard modes - all the same... Is there anything I've missed? It looks awesome - can't wait to play it through, and thanks for all the work on it. Wes Edited October 13, 2022 by wesmond typo Quote Link to comment Share on other sites More sharing options...
kski Posted October 13, 2022 Share Posted October 13, 2022 I was waiting with posting comment till I manage to finish the game (with default settings), but not so easy, although a few times I was already close. Finally I tried in Altirra and it was fast done - jumping is much easier with keyboard than with my joystick. First of all thank you very much for porting this game to Atari. Very appreciated. Indeed game is difficult, as for Atari game, some room with extra lifes as it was in the first part would help a lot. Becuase of the difficulty level I don't think I will come back to this game so often as to the original Bruce Lee game. But this is not any bug, only poor player problem... About bugs, it is possible to learn how to avoid most of them, but not all, what is sometimes frustrating. Anyway, most important, thank you again! Woj thank you for xex. 1 Quote Link to comment Share on other sites More sharing options...
tjlazer Posted October 13, 2022 Share Posted October 13, 2022 I tried the Commodore 64 version and man it’s hard. Especially on the screen with the 3 spikes coming down. This version is perfect in regards to difficulty. Quote Link to comment Share on other sites More sharing options...
