Heaven/TQA Posted January 15, 2008 Author Share Posted January 15, 2008 VIC 20 has 3 channels all in different octave. there are no options regarding sound just volume. Can someone please help me in transfering or adapting the VIC-sound values into Pokey? I would patch the STA SOUND0-Channel into JSR patch_sound and would return to the game after doing the POKEY conversion instead of scanning the VIC sound channels. Same thing I have done for the joystick routine. it's unbelievable how large the joystick routine of MetaLLamas is compared to a simple LDA STICK0... but ok... VIC-20 was developed several years ago as OEM video game chip but noone wanted to have one by MOS/CBM so decided to make a computer...

Rybags Posted January 16, 2008 Share Posted January 16, 2008 How many unique sounds does the game have? Might be easier to just do your own sound engine - obviously with improvements. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 16, 2008 Author Share Posted January 16, 2008 - increase level in start screen - entering level message - fire (done with 2 channels on VIC) - shot hits enemy - enemy hits player Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted January 16, 2008 Author Share Posted January 16, 2008 Miker... not bad... now i will try to implement them... are they played back like the sfx example in the RMT archive? (the same that i use in Beyond Evil) Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 16, 2008 Author Share Posted January 16, 2008 btw. should we stay as true as possible to the original or should we enhance little bit the gfx? f.e. with DLIs or music soundtrack? the c64 version is little bit enhanced...

Simple answer: Do both! One version as original as can be and another version that is enhanced. Regards, patjomki Quote Link to comment Share on other sites More sharing options...
miker Posted January 16, 2008 Share Posted January 16, 2008 are they played back like the sfx example in the RMT archive? (the same that i use in Beyond Evil) Yes, exactly - all except death "crash". I've made them very fast just before leaving my home (i was late in work, but no problems with it, hopefully). Regarding ingame music - i may try to do something but i'm now busy with another project. But maybe someone else will try to make some 3-channel ingame music. Or just leave the FX, just make them play on separate voices to avoid "cutting" the sound. Do as you want Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 (edited) ehm... can someone help me regarding Miker's soundfx rmt file? i am using the RMT-framework sfx.a65 in the archive... i exported Miker's RMT from RMT 1.26 with $4000 and the sound fx enabled in the export dialog. then I copied the feature headerfile into the rmt_feat.a65 and assembled the example but it does not work... anybody here who can help?

Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 ps. when i compare Miker's RMT file to the supplied SFX.RMT in the 1.26 then could it be that miker has the start-game jingle made like a song with 4 channels and so the RMT player is playing that (but interesting i can not hear that anyway...) and so all 4 channels are used? in the example RMT song line 0 is complete empty...there are no lines at all...

miker Posted January 19, 2008 Share Posted January 19, 2008 Heaven - look at the instrument names - they're corresponding with the task they are made for. The "song" at 00 position is just that "dead crash" mentioned above. And it has to be played as "song" as it was done on 4 channels for better effect. Is that (more) clear?

Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 Miker... that's clear... but the assembler source won't play your fx... Quote Link to comment Share on other sites More sharing options...
miker Posted January 19, 2008 Share Posted January 19, 2008 Ok, i don't know if player above can play FX only (without music playing at the same time). I've included corrected version with "blank" music (subsong #2 at line $02). And try to play FX on channel #0 or #1 and check if/how it works. sfxc.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 its interesting... RAM shows no music data... so there is some source code bug...maybe somewhere a typo... or RMT export issue... btw. Just listenting to your flower mania title track found in your RMT folder... what a great song!!! Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 (edited) its definitly some assembler issue... MADS won't compile the SFX.A65 correct and in my source which is 100% the same it does not load the RMT module to $4000... why the hell... ok....issue fixed... first lesson... save the source there where you think it will be when assembled (text saved the file to other folder than the one which i assembled all the time...tss...) second lesson... changed following in the source MODUL equ $4000 org $4000 ins 'mets_sfx.rmt',6 ;include music RMT module the OPT H- and OPT H+ are XASM specific and seems to be included in MADS separatly... now i have the sounds...

Heaven/TQA Posted January 19, 2008 Author Share Posted January 19, 2008 anybody any idea why RMT plays the instruments differently than the atari code? does the sound_fx player not support all type of instruments like the one with the c64 synth? mets_sfx.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 20, 2008 Author Share Posted January 20, 2008 (edited) nearly there... i would say 99% finished. - flashy colour bonus in place - text mode fixed (cbm font included for "original feeling") small issues: - raster bar fx - boundary bar flashing when hit by shot - sound fx (implement Miker's sounds) - decision overscan yes or not or patch gameplay/text to 20 chars screen. mets.zip Edited January 20, 2008 by Heaven/TQA Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted January 20, 2008 Author Share Posted January 20, 2008 here is a small overscan test... can you please have a look on ntsc and pal real maschines with TV sets? i can double check that only by tomorrow night... mets.zip Quote Link to comment Share on other sites More sharing options...
happymonster Posted January 20, 2008 Share Posted January 20, 2008 It might sound a little strange, but what about reserving one colour and then using that with a DLI to change the colour every scan line to get nice rainbow effects (possibly with the colours changing each frame too). This special colour could then be used for the laser, explosions and other bits and would add a nice funky colourful look. Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 20, 2008 Share Posted January 20, 2008 I feel that overscan wouldn't be "TV friendly" in a lot of cases. How about hard-scrolling via LMS? Show 20 characters of 22 - scroll 1 character left or right when the X-position of the player gets to within 5 or 6 characters of the edge of screen.

Heaven/TQA Posted January 20, 2008 Author Share Posted January 20, 2008 Rybags...exactly one of my options... maybe with soft-scroll... must be all VBL friendly as i have a "VIC"-framework running in the VBL...so the VBL could watch the x-position of the player and do the job...
