nice finding, I wonder what elso was different from the regular 520 ST?

nice one

It means that sometime it's worth to read the manual. BTW. I've found older version http://www.atarimania.com/documents/Madmac_Ref_Man_Jan-1990.pdf Where I can find the latest one?

For the last few days I was struggling with my code, which sometimes worked and sometimes it didn't Fortunately thanks to @dilinger Virtual Jaguar debugger I've just found an issue. It seems RMAC doesn't handle math correctly. Copyright (C) 199x Landon Dyer, 2011-2020 Reboot V2.0.23 Oct 24 2020 (Linux/OSX) Variables Test1 / Test2 should have the same value: nop LISTSIZE_FULL = 5 Base = $F00000 Test1 = Base + ((LISTSIZE_FULL*8)*4*4) Test2 = Base + (LISTSIZE_FULL*8)*4*4 move.l #Base,D0 move.l #Test1,D0 move.l #Test2,D0 nop nop But they don't:

my hardware is in my footer: Mega ST 1 / 7800 / Portfolio / Lynx II / Jaguar / TT030 / Mega STe / 800 XL / 1040 STe / Falcon030 / 65 XE / 520 STm

ok, I'll check that.

actually the connection is stable, I'm able to reset the Jag with jcp -r I need to investigate that issue further, but it seems that banging Sunkboard with skunkCONSOLEWRITE can sometimes screw it.

I have Skunkboard v2 (Sillyventure version) and I have faced a problem with skunkCONSOLEWRITE. After few jcp "run from ram" times following code causes a red screen after Jag reset ( "jcp -r") bsr skunkRESET lea Napis,A0 bsr skunkCONSOLEWRITE lea Napis,A0 bsr skunkCONSOLEWRITE Below My Skunk rom and jcp version: jcp v02.04.02 built on Jul 10 2016 Boot version 03.00.02, Serial 6510 Should I upgrade jcp and Skunk rom?

I do code on the real Jag, but in the first step I use VJ. I have Skunkboard, unfortunately it isn't stable enough - I observed that after using a few skunkCONSOLEWRITE in a row, when I do a reset with "JCP -r" I have a red screen with "Jaguar" logo and JCP is not able to connect to the Jag

I've faced the same issue. I have code witch works under VJ and doesn't under Jaguar. Would be cool to have equivalent of skunkCONSOLEWRITE (debug print just to DOS text console) in Virtual Jaguar. It would allow me to compare debug output for both Jagaur and VJ.

IMO most common configuration is 1040 ST with 1MB ram next is 1040 STe with 4MB (because easy way to expand RAM)

cool application @solidcorp

great progress @chicane

There is a comment by Drygol on April 1, in which he mentioned they should be available this week. https://atarionline.pl/v01/index.php?subaction=showfull&id=1611412343&archive=&start_from=0&ucat=1,9&ct=nowinki

There is a new USB adapter for the ST: mouSTer https://retrohax.net/the-mouster-project-is-here/ Works fine and it's firmware is regularly updated. And it's small what is important in case of the 1040 (I have mouSTer which fits perfectly and a second adapter from other vendor which is a bit to long for my 1040)

looks cool

ok, maybe it is my ISP issue, but I still have no access to it

doesn't work for me now

@cubanismo @Zerosquare good idea. thanks. BTW my Skunkboard Rev3 has bios "Boot version 03.00.02, Serial 6510" Should I upgrade it? If yes from where?

I meant that your program tries to install in "C:\Program Files (x86)\jcp" and Tursi's one I have placed in my dedicated folder. I prefer the second method.

#1 - for me ST/Falcon had well centered screen and they are reference. In additional, emulators like Steem have nice feature - possibility to extend visible border from normalt o large and max. #2 - ok #3- I've just sent him PM

unfortunately jcp.c looks similar in that area - "(paths are not supported)" that sounds really cool. one remark, would be possible to provide also portable version (just to install driver manually and nothing more)?

ok, mine is SillyVenture edition (v3 if I'm not wrong), and actually EEPROM is out of my interest at that moment. I'm more interested in communication with host PC. There are nice functions like skunkFILEREAD / skunkFILEWRITE / skunkFILECLOSE, but there are no for FOLDER manipulation. Would be possible to add additional functionality like open / close folder and create / delete file / folder? I'm trying to port EmuTOS to Jag and those additional functions would be very useful,

I have three observations where VJ differs from the Jag: Screen positioning: VJ - the screen is moved to top left vs my LCD TV. We can see that on following screenshots: Jag_Interrputs / VJ_Interrupts CPU/GPU accuracy: I did a simple counter on the CPU and the GPU. Left counter is the CPU, the right one - the GPU (value in hex) on screenshots Jag_GPU_CPU_counter / VJ_GPU_CPU_counter. And the VJ's CPU counter is 1.7 times faster, GPU's 2,4 times faster that the Jag. 68000 interrupts: When PIT timer interrupt is near to the VBL's one then VJ drops my VBL interrupt and the screen jumps. On the screenshots Jag_Interrputs / VJ_Interrupts we see pure dump of INT1 done during interrupt. The screen is 1bpp and INT1 is represented as 16 pixels. The VBL is lost when single dots are drawn on "VJ_Interrupts" Jag_Interrputs: VJ_Interrupts: Jag_GPU_CPU_counter: VJ_GPU_CPU_counter:

@cubanismo what was added in your version?
